Hi all just got my X1i today and when i turn on with my att sim card in there it shows "H" and i think that means "HSDPA" but isn't the X1i only have 900/1900/2100 Mhz? why did i got "H"??

Of course, the X1i can have HSDPA -why not?
That has been one of the most important things to me because I have much data transfer.
what i mean was i live in US so there should be no 3G or H signal that X1i should pick up since it only has 900/1900/2100 3G bands

Hmmm...this I cannot say because I don't know the networks in US. Isn't there another version for America -the X1a? I think I heard something like that.
Just can say, HSDPA works fine in Austria/Europe
ok as i know, US 3G should be 850 and 1900 bands and most of the Att 3G are 850 last time i had a diamond and it never went on to H or 3G at the same location, but this time it has H.

You say you have an X1i ?
What does Settings>System>About>Device ID say, please ?
Also, are you living in/near a city or in a regional area ?
ATT mostly uses 1900 for 3g. Also the H means you have HSDPA and HSUPA. If you only had HSDPA it would just say 3G.
yeah att use 1900 which 3g phones from outside usa can also use but
tmobile use 2100 or something
this is also the reason why people from europe can use american iphone 3g's
Saw this news story, does anyone know if it is credible? The NextG Service is on the 850MHz band which is the same as Rogers/Fido in Canada and Cingular in the US...if all this is true then one of these unlocked would be 3G Compatible in North America...Thoughts?

Well that would suck for me because about 3 hours ago I got an iPhone because I really needed 3g already I do ally of browsing and videos but I like the touch he better....
What is the exact issue with North America and the Touch HD? I thought HSDPA was fully supported in our continent under most major providers. Just curious as I'm looking at purchasing one in the future.

The Touch HD that is out now operates on UMTS 900/2100. Telstra in Australia and the North American providers (except T-Mobile) use UMTS 850.
hopefully it is just some software that HTC did. cuz we do have that option to change it to 850MHz 3G in the phone but just nothing happens to it. If a flash can fix it then it should be ok. EDGE for me is pretty fast anyways in Toronto most of the time.

850 mHz is just one of the 2 bands needed to work on US 3G. you also need 1900 . my understanding is one band is for upload the other for download. don't get me wrong, it would be fantastic if the Aussie version was fully capable on US networks. i'll believe it when i see it. heck, expansys even has a note saying they have to confirm the 850mHz 3G band.
850/1900Mhz....
could someone please explain the upload/download at different frequencies paradigm to me?

This is incorrect. With at&t you do not need both. With just 850mHz you will be more than fine.
Now with T-Mobile you would need both 1700 and 2100 not just 2100 or just 1700 both. Just more reason to hate T-Mobile.
I am ready to take the plunge and drop the $ for an HD. I also will switch my number back to at&t from verizon. I guessi cna say almost ready. I really dont want to spend $800 for no 3G
Does anyone know how hspa in Canada with Rogers/Fido works? i.e. are dual frequencies required or is 850MHz enough to get top speeds? Thanks...
Has anyone brought one into the US and had any success getting a 3G signal ?
Some carriers in the US and Canada use 850mhz such as AT&T and Rogers but they also use 1900mhz. It really depends where you live... Whiich city, state etc
1900mhz is growing in popularity in the states.

Sadly, no 3G for me.
You do not need both 1900 and 850. Its only tmobile that u need both frequenes but they use 1700 and 2100. As long as u have ether 850 or 1900 (depending on what freuency ur area uses) u will have 3g with at&t.

No, the *network* you use may be present on more than one frequency, but its not 850 being uplink and 1700 being the downlink.
When we talk about UMTS the downlink is around 850/1700/2100 but the uplink is always a few MHz below that. (to be pedantic, the UMTS specification specifies the exact downlink/uplink separation)
I can't imagine HTC producing a UMTS 850 phone that won't work on ATT/Rogers and Telstra . Telstra only needs the 850 band so HTC can add in whatever extra the US providers use. It will probably be the same bands supported by the HTC Hermes and other phones common to these providers.
for AT&T, you do NOT need both frequencies (850 and 1900) for 3G. They don't HAVE both frequencies in most areas. It's one or the other.
And yes, T-Mobile US sucks ass...

Well I stand corrected then. This is good news then. Just need somebody in the US to buy a Telstra HD and see if it works. I guess it will be dependent on the area though. If you don't have 850mhz.
Lol i guess it took a senor member to say it for anyone to believe it. I only said it in the first page lol. Lets see what happens when the aus model comes out.
So it is decided then IF the Blackstone is introduced by Telstra and working on their 850MHz 3.5G Network THEN it has the opportunity to work in both the US on Att and Canada's Rogers/Fido...I will wait for this device, purchase it and let the board know if someone else doesn't beat me to it!
P.S. does someone think that this release may be with the Android OS for Telstra? It was the Telstra reps that were commenting at CES 2009 regarding Palm Pre and how the next Android phone that they were testing kicks it...who knows probably coincidence...
I have a GSM Touch Diamond and there's no way to use the US 3G even if you have a 3G sim, we discussed it in the Diamond forum and people said it's just not possible. Is this the case with the Blackstone or are you able to use 3G in the US?
if you use a 3 sim you can get service if 3 got a roaming agreement with an usa isp
if the usa isp don't use 3g services on the hz's the rest of the world use you can only get
2g or 2.5g (edge) service
the Telstra Touch HD version (Blackstone - T8285) uses at&t's 850 3G band. it works quite well in the US as long as one is in an area that uses more 850 3G towers vs. 1900 3G towers.

it's 3G from at&t, period. as i mentioned in my post, the Telstra HD is limited to using at&t's 850 3G band. at&t uses both 850/1900 to deliver 3G. if you're in an area that uses only/more 1900 3G towers then you may not have 3G access. i believe Phoenix, AZ is an example. can't comment on the speed with an at&t phone because i don't own one. the pic below is an example of the speed i get with my Telstra HD on at&t.

If there's 850 towers but more 1900 towers then the 3G just won't work at all? It won't just connect to the 850 ones?
I live in Houston, TX and commute between there and Austin, TX.

i can't say if it won't work at all. for example, if there are 100 towers and 95 are 1900 and 5 are 850 and, you live near an 850 tower, (theoretically) you should get 3G access. using your example, i would say you'd be connected to Edge more often than 3G.

if i remember correctly, there's a user here named tucomora who lives in Houston and has a Telstra HD. i believe he indicated that Houston may have more 1900 towers than 850s. but, as you may know, at&t is adding more 850 towers nation wide. i suggest you send tucomora a PM to get his perspective on using the HD in south texas.
http://forum.xda-developers.com/member.php?u=251104
I looked for tucomora, tucamora, tacamora, couldn't find anyone.
Would you not be able to go into the phone's settings and disable the 1900 band or something? I have a Diamond on AT&T now and it's between upgrading to an HD or waiting another month and signing up with Sprint for the Touch Pro 2 (or Palm Pre now) and then just looking like an idiot carrying 2 phones around.

why would you want to disable the UMTS 1900 3G band? if there are no 850 3G towers, you won't get 3G service you'll get EDGE instead. my phone options are set to Auto for GSM and UMTS and if there are no 850 3G towers it switches to EDGE. simple as that, not a big deal for me (and not implying that it is to you). you can change the GSM/UMTS settings to seek/use only 850/1900 3G towers, but in my experience, if the HD doesn't find an 850 3G tower, i won't have a phone signal, period. if you're in the US and want a HD with 3G capabilities, you get the Telstra Touch HD and accept the fact that having only one US 3G band (e.g., 850 3G) will limit 3G access in some areas.

If there are 850 towers but just not as many as 1900 towers, you could disable 1900 so it only connects to the 850 towers and then you'd have 3G, right? That's what I was saying. I have EDGE on the Diamond but it's so slow it makes me not want to use it most of the time.

uh, no it doesn't work like that. the phone is going to lock onto the strongest signal possible. if it sees a stronger 1900 signal, that's what the phone will use. if you (could) disable the 1900 band and you're in an area with 1900 towers, you would not have ANY signal at all, no phone, no data. based on your level of concern, wait for the at&t TP2 (or whatever it's called); then you'll have no worries about 3G access.
Thanks for all the help, I just ordered the T8285 so I'll let you know how it is. Will I be able to use all my Diamond accessories with the HD (extra batteries, chargers, etc.)?

chargers yes, batteries no. The Telstra ROM that comes with your device will have its internet connection settings locked to Telstra (which we can't obviously use in the US). this means you won't be able to access the internet from your phone until you add at&t's connection settings. i never researched methods to add at&t's connection settings so i don't know if they exist. i flashed HardSPL to my device so i could install a custom ROM. i suggest you click the link in my signature and learn about flashing new ROMS. hope you enjoy your device!

T8282 battery works with T8285. essentially, accessories for the T8282 work for the T8285. the only difference between the phones is the radio bands.
I'm looking to possibly get this as my 1st android phone - but I would like to be sure that you can get 3g on ATT in the US.
Any confirmation would be helpful.
thanks.
Edit: NM I found out the sad news
You're missing the point. GSM quad band is for 2G service only. In order to get AT&T's 3G service, you will need both 850 and 1900 UTMS/WCDMA band support. Obviously the current spec is for use outside of North America. If and when Samsung descides to bring it into NA, it has to add either AT&T's 3G band support or T-Mo (1700/2100) 3G band support.

Just for reference.
yes you can get the i9000m version and you get full 3G coverage on both 850 and 1900 bands
don't get the i9000 version as that is only 900 and 1900 bands

You don't need BOTH (850 and 1900) to get 3g. You can get 3g with just 1900mhz, but it's definitely preferable to have 850mhz and 1900mhz.
So get the i900m.
true and not true
only having 1900 band have a disadvantage
specially when you go underground or into buildings and areas outside of the big cities

I am simply trying to convey the message that a phone with 1900mhz 3g can in fact connect to AT&T 3g network. I am not saying or have ever said that you can get it everywhere where AT&T provides 3g service. Jeez.
I haven't seen any specs for North American Galaxy Tab so I don't know if the AT&T version will have UMTS 850. I have ordered a Euro version that has UMTS 1900 so I presume it "should" work on AT&T 3G but I'm worried because what I can find on this subject implies UMTS 850 is essential for AT&T 3G. Can anyone with experience in US tell me how well the UMTS 1900 only works? Thanks.
Yes
To be more specific, it will if your city still has the 1900 mhz band. Check here: http://www.cellularmaps.com/att_850_1900.shtml

Thanks for the quick response and the maps (first time I've seen coverage maps by frequency, since AT&T no longer offers them) Very helpful and I feel better about haven ordered the Euro version.
Are there any owners of cellphones using the Euro 900/1900 UMTS frequencies on US 3G networks who can share their experience?
I live in the SF Bay Area and here the network is mainly 1900Mhz so the device works very well.
If you live in a market that got 3g fairly early, your network in probably 1900Mhz.
If you live in a market that only recently (1-2 years) got 3G, you might be on a 850Mhz network.
