anybody in new york or been to new york with your athena to see if it works with the new upcomming t mobile 3g network? they say its running on 1700 freq.
anybody have luck or an answer for this one?

that would be a no then, 2100Mhz is what the athena is capable of AFAIK
I have used the Athena on both T-Mobile and AT&T Networks in the US without issues.
I also have had no problems with T-mo in my area (central NJ) using 3g. I'm using an x7501...TJ

that seems odd, Current roms do not have the T-Mobile US band included, nor is the current radio capable of running the t-mobile 1700 band in the USA. ATT band is 3g/UTMS 850/1900 and Europe is 3g/UTMS 800/2100
T-Mobile Edge would work fine though
Hi, sometimes the 3g pop's up on my x7501 its not all the time but next time it does I will take a screen shot of it. Maybe its an error I have no idea...TJ
some roms incorrectly show that instead of edge !
Ok thanks...TJ
So is it possible to get T-mo 3g on athena?
T-mo finally rooled out 3g in my area, I thought my athena was 3g capable and could fly through the internet and never deal with slate Flinstone tablets and EDGE again! Sadly we do?
Their 3g is rolled out on 1700/2100 band only, so to exit the EDGE stone age, we must buy the G1 (not even close to x7501) or ask a crazy question to those in the know. Is the frequency band offered on a phone limited and fixed by the ROM / hardware, or is it software driven where a patch / upgrade could expand it's operantional band to include 1700/2100 UMTS alongside the voice 850/1900 band?
I can connect easily to TMobile. I get the "E" sign showing on the antennae.

It is hardware driven. Unfortunately this is why I'm going to switch over to AT & T because of the downgrade to get 3g service from a phone that NO OTHER Networks in the world uses is pointless IMHO. I don't know what T Mo was drinking or smoking, and when I asked the level 1 techs they said no future talks or expectations of using the NORMAL 1900/2100 Frequency like other 3g networks. Sux if you ask me.
Thanks for the note on hardware capability
I got similar responses from the techs at T-mo except I also got a moment of false hope when one incorrectly told me that their 3g is on 1900, I went nuts trying, then called back & someone else told me that it was in fact on 1700/2100. As I've been reading, their reason (though a huge pain in the ass for us) was to separate voice and data so one wouldn't steal bandwith from the other. Makes sense, though it would be easier to deal with if I had some REAL options other than G1 and crappy kids phones.
Since T-Mo has the best price for some pretty decent service (except EDGE that is), I've heard of some T-Mo users getting just an AT&T data plan alongside T-Mo voice, I'm not sure how it's done, do you need 1/2 simms, or what. If you find yourself doing this, I would like to hear your feedback.
Otherwise, I'll keep my fingers crossed that HTC will use some common sense, and use 1700/2100 in future US versions.
Ok so I was looking online at the HTC site and see its says:
Network HSPA/WCDMA:
* Europe: 2100 MHz
* US:1700/2100 MHz
* Up to 7.2 Mbps down-link (HSDPA) and 2 Mbps up-link (HSUPA) speeds
Quad-band GSM/GPRS/EDGE:
* 850/900/1800/1900 MHz
I honestly do not know what everything means but I know that ATT's 3G runs off of 850 and 1900....am I correct?
If I am then the ATT 3G should work correct? I am trying to figure this all out because I may pick a G1 up tomorrow with my little brothers account seeing that I am with ATT as of now in order to get the Touch Pro.
THANKS
No it will not work on att 3g
well i guess its not down to if I want a phone with no 3G?
Think its worth not having 3G?
No dude, get a phone with 3G. Honestly when I'm stuck in an EDGE area with my G1 it's too slow for me to do much more then IM and stuff, I almost always switch to my Sprint rev. a pda when out of 3G. Also, more and more services will come out that use 3G and you don't wanna get stuck behind the curve.

I've had my G1 for two days now and I am in an edge area (no 3G). I'm sure it is alot slower than 3G, but my phone is fully capable of doing anything that it is suspose to. Loading a webpage takes less than 10 seconds. Loading apps from the Market have taken me less than a minute. I'd say this phone is very capable if only on Edge.

I am also in an edge area (3G starts a few miles away). I cannot stream podcasts, but tbh the only time I find myself doing that is when I'm stuck at the airport. Websites load up quick enough...
Right now 3G coverage is only absolutely required if you are tethering or streaming media. I have wifi for my off time at home so no biggie. Now I know there will be some apps that will require that kind of bandwidth, but hopefully tmo will have expanded 3g to my area by then.
Hello,
I was just wondering if
HSDPA/WCDMA: Europe: 2100 MHz / US:1700/2100 MHz
means the G1 has both the frequencies for Europe and for the US
or it is sold in 2 Versions.
Does anybody know?
Thanks

The G1 is dual-band UMTS; there's only one version.
A tip though, NEVER use frequencies to refer to UMTS bands; they're confusing and ambiguous. Always use the numbered bands.
AT&T uses bands II and V, T-Mobile USA uses band IV, and Europe uses band I.
The G1 supports bands I and IV.
All AT&T 3G phones support II and V, some support band I in addition.
Here's a good article listing the UMTS bands:
http://en.wikipedia.org/wiki/UMTS_frequency_bands
There are NO phones to my knowledge which support BOTH bands IV and II or V.
What that means is that you can follow a simple rule, at least for the time being:
If it supports T-Mobile USA 3G, it doesn't support AT&T 3G.
If it supports AT&T 3G, it doesn't support T-Mobile USA 3G.

Have a great weekend all.
I hope this not a problem posting this here. I am from Delaware and I am trying to get rid of my iPhone 3gs and get an htc magic with AT&T 3g bands. I am having no success with craigslist, it is flooded with iPhones. If anyone out there has a htc magic in great condition with warranty and wants a iPhone 3gs with a full zagg invisishield already on the phone. Please contact me at
[email protected]
Won't happen.
The Roger's Magic isn't going to put out the 3G capability you're looking for on the AT&T frequencies.
It would have to be properly scaled and designed to function on those frequencies, which it isn't. If a phone is GSM, that doesn't necessarily mean it can output the 3G speeds on any GSM provider. The MHz bandwidths need to be the same.
htc magic at&t 3g
Can anyone else confirm this, I have read multiple forums that have said that it is possible. The specs for Rogers say UMTS 850,1900 which is the same 3g freq. that AT&T uses.
It works with Rogers HTC Magic
I can confirm 3G works on AT&T with the Rogers HTC Magic.

Rogers uses the same bandwidths that ATT uses.
This is for the reason that Rogers used to be Rogers ATT.
I can confirm that my HTC Magic from Rogers gets 3g.
I was lamenting on my lack of foresight, getting a HD2 without researching the different bands that AT&T and T-Mobile use for 3G coverage, when just the other day...
NOTE: This was on a call to AT&T Support and the tech tells me:
a) Once unlocked from TMOUS, I should do a search on "AT&T APN's" and that if I search diligently, I will find APNs on AT&T's network that support HD2 3G Bands
b) AT&T techs, right in his data center have this working.
So I research a bit, and, apart form everyone and his brother professing to be 3G Band experts, and saying all I will see is Edge if I put the HD2 on AT&T. (Which is troublesome, since Wikipedia claims Edge is being dropped to facilitate more 3G bandwidth, so potentially I would lose even THAT).
Here is what official information I could find on the two:
The U.S. T-Mobile network predominately uses the GSM/GPRS/EDGE 1900 MHz frequency-band. T-Mobile's UMTS (3G) service is now active in over 30 major US cities
Further all official documentation states that AT&T uses:
* 850 MHz UMTS/HSPA/HSPA+ 3G
* 1900 MHz UMTS/HSPA/HSPA+ 3G
Finally look at my screenshot, taken from the GSM 3G toggle on the "Settings Tab" of Manila. I am running a NRG ROM (see signature) and I KNOW this is wishful thinking. This screen in particular is no doubt a function of the many devices NRG cooks for, but really, can anyone explain to me why this technically would NOT WORK (other than "just because", LOL)?
AT&T's CEO recently gave an interview and stated that the company's 3G service is being migrated to the 850MHz band with a target date of 2010:
http://www.intomobile.com/2009/02/24/att-3g-network-going-850mhz-nationwide-by-2010.html
For what it's worth, I think the Australian version of the HD2 might have a band that overlaps with US AT&T bands.
Whos gonna buy me one?

Yes, I have been hearing the same. Problem is, I am not likely to fork out $$ for ANOTHER HD2. I just wanted to get the most out of the one I have. Thx!
if something like this WAS possible, it would have to be through something like a rogue apn setup on non-standard frequencies on ATT's network...but good luck finding anything like that, it wouldn't be able to remain a secret if it existed. also, if the hd2 had the ability to use those native frequencies, it would have had to have been certified as such by the FCC (which of course it wasn't).
To summarize, the only way to make it happen is if ATT did indeed somehow sneak in alternative-frequency apn's across it's entire network. Let us know how the search for those turns out

Sorry.
http://en.wikipedia.org/wiki/T-Mobile_USA
3G (UMTS/HSPA/HSPA+) service by T-Mobile exclusively uses the AWS 1700/2100 MHz frequency-band, making it incompatible with other existing 3G UMTS/HSPA networks already established in the United States.

Its not physically possible. The hardware would have to be changed. They don't make radio chips with all the bands in it. I see this all the time, some random csr from whatever company says it can be done, but its just not true. Cell phones are designed and made for a specific company. They don't make universal radios and just turn off some bands. They don't exist, though I did read a few months back that Motorala was working on making one.
Although I understand the reason for your wishful thinking (and you did do some research which is always great), unfortunately it is just that and I'll gladly (though not happily) tell you why.
As you stated "U.S. T-Mobile network predominately uses the GSM/GPRS/EDGE 1900 MHz frequency-band" which is correct (and it also uses the 850 band for edge as well....though this is usually more 'roaming' aka you're using another companies cell tower because tmobile made a contract with them to allow you). You were also correct in stating that "Further all official documentation states that AT&T uses:
* 850 MHz UMTS/HSPA/HSPA+ 3G
* 1900 MHz UMTS/HSPA/HSPA+ 3G"
Also, ironcroth was also correct in quoting that "3G (UMTS/HSPA/HSPA+) service by T-Mobile exclusively uses the AWS 1700/2100 MHz frequency-band" which alone might not answer your question.
So where is the problem if both use 1900 and 850 bands? Well, the problem is that in the hardware, there is a difference between GSM/GPRS/EDGE and 3G/UMTS/HSPA/HSPA+. In other words, you can't use 1900 and 850 Edge frequency of the HD2's radio chip to get 3G (UMTS/HSPA/HSPA+); they are incompatible. This is why phone spects always list both seperatly and not just all the frequencies that it supports.
The above reason alone will make the TmoUSA HD2 incompatible with AT&T's 3G, but there's even more. When Tmobile says that it uses the (for example) 1900 frequency band for Edge, it doesn't actually mean that it uses 1900-1999 frequencies; instead it only uses a part of that spectrum (buying the full 100 frequency range would be expensive so they only buy what they need). Instead they only use maybe something like 1943-1978. And this range will likely not overlap with the frequncies that AT&T uses for their 3G (you can look up the exact values on the internet if you'd like). This second reason is why a european phone which supports 2100 band for 3g will not work on Tmobile's 3G 2100 frequncy (because they don't actually overlap).
Lastly (and I almost forgot to mention this), the screen shot you posted from your ROM can indeed be changed by a cook to whatever they want (though it won't actually make any difference since it all depends on the hardware). However, in this case, it's likely because htc actually made the error and never updated that screen and just used it from their previous builds from previous phones (this was stated on the forums before and I'm sure you'd be able to find it given some searching).
Hope this helps.

Quite unlikely, the AWS bands are licensed to TMO, im sure TMO would notice real quick if there were unlicensed cell towers on the AWS band and the FCC would be slapping ATT with fines pretty quick. quite alot of work goes into setting up cell towers and the frequencies each cell segment runs on, If a rouge cell tower went up overlapping TMO's frequencies, all hell would likely break loose as far as customers being able to get usable service in the area.
also as far as the terminology APN's don't operate on a "frequency" an APN is more or less and authentication/proxy server on the data network after the data has transferred over the air interface.
Maybe the best way to think of it is similar to a cell tower being like a wifi access point, and the APN being like an authenticating router/firewall on a standard tcp/ip network. yeah i know its not quite the same, but that might be a simple way to visualize it for those familiar with networking

Haha no, though i do have scanners and listen in on HAMs sometimes and have read up on the stuff somewhat. never gotten myself licensed.
On the subject of scanners, there isnt all that much interesting to listen too anymore. Here in tampa the police and sheriff are on analog trunked now, so its impossible to follow anything without a trunking scanner, and about the only other things you can listen to are cabbies, tow truck drivers, aircraft, and hams. I don't even know why scanners still have the 800mhz blocks anymore, analog amps cellular has been dead a few years now. you find lots of digital noise scanning around though, just about everything is transmitted digitally now. i've got an icom R20 that goes from 150khz all the way upto 3ghz
So why don't you put in an AT&T sim card with a 3G data plan and let us know if you get 3G on your HD2?

Thank you very much. I myself had been wondering why I couldn't get an HTC Desire (honestly, pretty much the only phone I'd change my HD2 for unless a GSM version of the Supersonic becomes available) and have it work in the US at the 2100 frequency.
When I asked before, people would tell me that a phone would have to support both bands (1700/2100) to actually run on T-Mobile because one did HSDPA and the other did HSUPA, but that didn't make sense to me since all you need is a single band frequency to handle both D and U data streams.
Your explanation makes a lot more sense. It's a sad thing, though.
I remember reading somewhere that a chip manufacturer (motorola?) was working on a all frequency chip. I also read that the inherent problem with that would be the antenna.
It would be awesome to have an all band phone that world travelers could utilize. I love the HD2, I had upgraded from a long time use of a Treo 750. That phone was pretty close (quad GSM, triple umts). However when Tmo rolled out it's 3G on 1700 I was still stuck on edge with the 750.
Finally bit the bullet for an HD2, really like this phone. The 750 seems antique now heheh

Building a multi frequency chip isnt all that hard. software defined radios have existed for quite some time. basically a simple reprogramming allows it to xmit/rec on a different frequency. the trouble comes in the antenna design. antennas must be designed to work at specific frequencies to be the most efficient at transmitting and the most sensitive at receiving. trying to make a single antenna capable of xmit and rec anywhere in a bandwidth ranging from 700mhz upto say the 2500mhz that wimax uses, is going to make for quite a ****ty antenna at any frequency. When you see the piece of foil antennas in todays phones, they may just look like a simple piece of foil, but a lot of design goes into them to make them work well at the frequencies they need to work with.
I guarantee if you compared the internal antenna of the Euro, AUS and USA HD2 there are slight differences. Ill bet the radio chip in them is for the most part identical, there may be something modified on them to keep people from interchanging the radio roms between them though since that would invalidate any FCC or other country equivalent certification for that phone to operate
Its one thing to run a hacked rom, its something completely different to use an uncertified radio rom. Could cause all kinds of havoc with the cellular network, and get slapped with FCC fines if they could track down your trouble causing phone

Yeah that's on par with what I had read, you do well at explaining it.
Maybe some futuristic worldphone designer would opt for interchangeable external antenna's... I could live with that or maybe multiple builtin foils with a software driven switch between them and the radio... that would be neat. Not holding my breath though...
Interesting on the FCC, hadn't thought of that.

Thanks, I was just again looking at the spec differences between the euro and TMO HD2s and i really don't know why HTC did not also give the TMO HD2 850/900mhz HSPA/WCDMA to truly make it a world 3G phone. According to the tech specs over at HTC.com, TMO HD2 can already use 850/900mhz for GSM/GPRS/EDGE so the antenna is obviously quite capable of both. The only other frequency the TMO HD2 has to handle that the euro doesn't is 1700mhz
Part of me thinks it was probably done so the HD2 couldn't be used over on AT&T

It had nothing to do with AT&T, it's because there's a difference between Edge and 3g radio frequency. More than that, there is no phone radio chip that supports all those frequencies and even more so, htc doesn't manufacture radio chips, they purchase them and put them in their phones....just like the majority of the hardware

I think this is incorrect -- the 2100 band support on the HD2 is in fact expressly intended for 3G compatibility in Europe/Asia, and people have reported being able to get 3G in Europe with their US HD2.
1700 == US-only 3G
2100 == Europe, Asia 3G
What's missing, I believe, might be 3G support in certain areas of places like Latin America which may follow US frequencies but don't have T-Mobile USA there to provide 1700 service... e.g., no 2100 and no 1700 either.
T-Mobile U.S. uses both AWS 1700mhz and 2100mhz for 3G. The 2100mhz band is used for transmit and 1700mhz is used for receive. Hence the incompatibility with other carriers phones that only operate in one spectrum.

Just curious if anyone is using the MT4G on AT&T and how well that's working? I know we can unlock it for use with any carrier but wanted some feedback before I spend the money to get my gf (now using iphone 3gs) an MT4G to use on AT&T.
I already know that 4G won't work. I got her a Captivate for Christmas but she really likes Sense and AT&T's phones are so locked down it's stupid. Can't use custom ringtones, can't sideload apps, etc.
Can anyone help out?
So I'm doing some research and it looks like there's minial wcdma overlap which means spotty 3g coverage? Is that right? I really don't know how to interpret what I'm seeing though so I would be really appreciative for the input of someone more informed than I.

i am using my MT4G on att and its preety good reception wise. I got 15 dollar unlimited data plan. Bec this is tmobil made hardware so i only get edge.
Why not just grab her an att nexus one and flash sense into it? Evil D's ports are really good!

3G won't work either. My question is why on earth would you want to take a MT4G over to the [IMO] worst network of all time?
Only bands 1& 4 right?
Although the captivate supports 2100, at&t only operates 850 & 1900 in the us. Some phones have 2100 for global roaming because that's what most others use.
While at&t does have a larger footprint, I just paid them $180 to get out of my contract and I'm much happier with tmobile. Texts actually send and web pages actually load.

It works just fine, just slower, obviously.
And yes, it is 3G.
Let me be super clear about this... 3G WILL NOT WORK on AT&T. The MT4G just doesn't have the right radio. However, the Vibrant (surprisingly) does have the 850 band on its 3G radio, and does sort of work for AT&T.
If you want an Android phone on AT&T, I recommend buying something unlocked from Canada. Rogers and Bell both share AT&T's 3G bands (850 & 1900), and have a better selection than AT&T itself.
Really great comments here. She's got a year left on her contract, that's why. She's gonna find out her termination fee tomorrow cuz she loves my mt4g, lol.
I always knew that an N1 is definitely her best bet but can't find one used and have an mt4g in the works for $260.
We're talking slightly different things here as well. HSPDA on ATT won't work.
However, "EDGE" describes a family of service classes, not a single speed. Depending on your location and the service speeds there, EDGE may in fact be qualified to be called 3G according to the ITU (the international body that certifies this nomenclature).
As the radio in this phone most certainly does support EDGE, whether or not you can get 3G speeds on AT&T will depend on your location. For most of us this will still be a "no," but if the OP is in one of the special markets (LA, NYC, ATL) you can see it. Since OP is in Oakland, I figured he might get lucky.
I swap cards a bit on mine (one SIMM or work, and one for personal use) and have been in areas where the EDGE network was nearly as fast as the supposed 4G on the other card.
I should probably start using the that bandwith meter app and record my results. It could be interesting.

EDGE is not generally considered a 3G technology, although it is a significant improvement over GPRS, and it offers speeds approaching true 3G speeds.
Calling EDGE "3G" is somewhat like T-Mobile calling HSPA+ "4G"; it's playing a little fast and loose with the definitions. I do agree that in ideal circumstances, EDGE speeds can be pretty good, but it really falters when it comes to streaming media or any other data-intensive task.
