Not trying to start any problems with my first posting but, The 3G icon on my touch hd has change a few times during since I purchased it, Does anyone know if this has been caused by any changes with EDGE.
What do you mean by has changed a few times? You never got 3G in New York did you?
The 850mhz bandwidth was converted from 2G to 3G. http://wmpoweruser.com/?p=2195
"AT&T is apparently changing the 2G and EDGE band, from its current 850Mhz to the weaker 1900Mhz. What that means, is that devices without 3G capabilities, like the original iPhone, will have to cope with the reduced coverage that the new 1900Mhz band has. In the other hand, devices supporting 3G networks like the AT&T Fuze, Tilt, Epix etc, will only benefit from this upgrade, as the 850Mhz band provides much better coverage, especially indoors."
Are you really getting a 3G signal in NYC? If that's the case I'm buying one
My Edge (E)icon has turned to G on about 20 occasions since purchase two week ago.Its not a steady G but will last about two minutes and then goes back to E
Interesting that you posted this. I am using my THD in NYC and NJ areas with T-Mobile USA. I have also noticed that the "E" icon on my THD had changed to "G" at some areas in NYC. But I have not noticed any difference in the data speed.
I just thought that my phone is able to acknowledge the T-Mobile 3G signal, but does not have to facility to access it. I do not know the technicalities behind it.
Isn't the "G" icon for a slower connection than EDGE? i.e. GPRS
yes!!!! now we have firm confirmation that touch hd is capable of 1G and 2G (EDGE)

What this means is that us in the usa better hope that we can enable 3G on the HD soon.
ya. even if tmobile does require both bands, one for down and one for up, it'd be nice if only 1 workded (down) and we were able to at least be able to DL quickly or something. any speed boost is better than none
Just to throw it out there:
Don't know if it is 3G but my "E" changed to "G" on few occasions, for few minutes here in LA, CA (T-mobile). I didn't sample the connection speed, however; thus, wasn't able to tell any difference with the download speed. Edge is good enough for my usage, tbh.

G = gprs 1G which is not 3G and it's slower than Edge 2G....
When I look at the G settings
Its says GPRS,3G

You guys...these are the icons you'd expect to see on your HD for GSM coverage in order of speed:
G - Normal GPRS data
E - Enhanced Edge data
3G - 3G coverage
H - HSDPA, 3G turns to HSDPA on some networks while downloading data then switches back to 3G a few seconds after data use.
If you are seeing a G on the top bar, it means the HD is in the slowest GPRS data rate mode.
Thanks for the clarification, guys; I thought so. Oh well, no need for wishful thinking, then. 2G or not 2G...blah, curse you Hamlet!

max speed technically...(at least in Germany)
GSM:
G --> 56kps (0,05MBit/s)
E --> 256kps (0,25Mbit/s)
UMTS:
3G --> 384kps (0,38Mbit/s)
HSDPA --> 3,6; 7,2; 14.4 Mbit!!! (depending on operator) --> sometimes called 3.5G
LTE (long term evolution) --> 4G (Generation)
coming in 2010 from 25Mbit onwards
using opera, just for surfing, i think EDGE is enough. (without using flash in opera)
regards
irm
p.s. @galaxys: the old analog network is to be considered as the 1st generation; GSM (incl. EDGE) is the 2nd generation. EDGE is some sort of speed upgrade like HSDPA for UMTS.

Your saying that it said 3G on the top of your screen not just G? If so can you post what rom/radio you are using?
You can find this in settings/system/device information

Is this on the top bar or is it the popup network setting bubble? Take a pic for us...
There is a setting, probably hidden and changable via Advance Config and/or HD Tweak where if a network has 3G capability then it shows "<network> - 3G" (I disabled it via one of them)
This is regardless of whether your phone itself can handle the 3G network, which in the case of Touch HD it cannot as the device does not support the frequency of US 3G bands
Mine shows "O2 UK - 3G" for this reason regardless of whether it says G, E, 3G or H at the top of the screen.
Additionally, the "generation" things are as follows:
- - GSM - 1G
G - GPRS - 2G
E - EDGE - 2.5G
3G - UMTS - 3G (surprise surprise)
H - HSDPA - 3.5G
I have a question regarding the HSDPA on the TMOUS HD2. I used a Diamond back in Germany and when I was in an area with HSDPA reception it was indicated by a "H" in the taskbar. Now I am using the HD2 in Baltimore. From what I`ve read there should be HSDPA available arround here (especially since I am in Downtown B`more) however I only get the 3G symbol in the taskbar. I have also been in DC over the weekend and it was the same only 3G. But I am quite sure they have the HSDPA network available there. Does that mean my HD2 doesn`t get the faster HSDPA speeds at all?
I did a speed test using mobilespeedtest.com and IE.8 teethered WiFi connection on a Windows 7 system. My results in Downtown Baltimore are: "Your speed: 1428.571 Kbps Your latency: 0.561 seconds Transferred 100 KB in 0.56 seconds". With a 4 bars 3G symbol instead of a H in the taskbar. Aren't this speeds you would expect on a HSDPA network? I am running the original stock ROM on my HD2 by the way.
I am pretty sure most carriers use 3G with hspda enhancements, aka 3.5g, which would allow the speed above 3G's cap (364 kbps). As far as why your phone states H instead of 3G, it is dependent on the phone and icon set your phone uses. Some roms will show 3G and others will show H.
where do you find the HSPDA settings? I know they were somewhere but I can't find them!
I think the 3G/HSDPA is weird on the HD2. I can sit in one place and watch it change from Edge to HSDPA without moving the phone (and sometimes a random 3g will show up).
It definitely sounds like you have HSDPA since those are some nice speeds. Mine says 'H' and I get around 780kbps, so you're double that. As long as you have a fast data transfer (and you do) I wouldn't worry =)

I was in Las Vegas Convention recently, and witnessed the power of HSPA+.
HOLY CRAP. Why can't we have that speed ALL over the world?
I was always under the impression 3G was better than H. Perhaps it's a good thing then that mine's usually H then! Where does E fit into the speed scale?
E = Edge. the slowest.
actually GPRS is even slower than EDGE
if i remember EDGE = 500kbps
GPRS = 360kbps
GRPS = 2G
EDGE = 2.5G (sorta)
3G = 3G
H (HSDPA) = 3.5G
Just got the G2...awesome so far...only one annoyance. The tmo HSPA+ network has been available to me almost everywhere (in houston) but it seems to switch to the Edge (3G) network whenever it wants? Is there a way to force or to stay on the 4G network? Thanks!
GPRS (G) AND EDGE (E) are both 2G technologies (EDGE is on top of GPRS). 3G is UMTS, and HSDPA is again on top of UMTS. You can find a setting for 2G only in Android options, but there is nothing to force 3G speeds. The reason is that phone uses HSDPA all the time unless there is no HSDPA signal, then it drops to EDGE, or GPRS.
So you cannot force it, it's defined by what can the mobile network provide at that specific spot. If there is no 3G/HSDPA coverage, you have no 3G speeds. It is as simple as that. It's like if you would like to use WiFi even at places with no WiFi coverage - you cannot, because it's not there.
Ok, but lets say for instance sitting at my desk at work i'll be connected HSPA+ for 10 minutes and then it drops down to Edge? Whats the reason for that?
You were at the the borderline of what is and what is not a acceptable level of signal from the network tower. For 10 minutes it was above the limit, then it dropped and it was not more usable, so the phone dropped to lower speed.
thanks for the explanation man!
Wrong forum though. This this about having separate G2 and DZ forums is bound to lead to lots of this, I guess.
I just got my NS a few days ago, and I'm using it on T-Mo. I've noticed it's on UMTS 95% of the time even though I'm in a HSDPA area which is blanketed in HSPA+. There is a difference in speed so I'd like to figure out why it's not connecting to HSDPA.
Anyone else noticing this? I called T-Mo but they blind transferred me to HTC :WTF:
Just checked mine and it is also on UMTS. My area is also HSPA+-erized, so I should be getting HSDPA. Might be because I am in my basement though. I'll test it outside soon too.
hmm HSDPA here
I think the t-mobile 3g network camps on umts all the time till a data stampedp occurs where it quickly switches to hsdpa, then back again. However on ATT for example shows hsdpa the whole time no matter what.

I'm starting to think this is the case. I saw 5+ Mbps down tonight even though it showed UMTS the whole time. No way that could be UMTS
Just a bit of a curious observation. Coming from the US almost 2 years ago, while connected to a HSPA network, my android would always display the 'H' icon, whether in a state of active download and/or uploading or not. Occasionally, it would fall back to an E logo for the EDGE network within buildings, etc.
Now, here in NL, over the course of 2 years I've subscribed to two different providers and both exhibited similar behavior (KPN and Vodafone for you Dutchies). Within good reach of the towers, my phone shows the 3G icon, but when actively downloading or uploading something, as exhibited by the up and down arrows, the H icon is immediately displayed, and when active DL/UL stops, the H icon changes back to the 3G icon.
Is this constant switching a network-capacity measure taken by the providers here to limit the number of devices communicating with the faster (H/H+) equipment?
It may depend on the type of UTMS. It may be DC-HSPA down to another form. It could just be your ROM too.

Depends on the network you use. If your network supports UMTS (displayed 3G in android) then your connection falls back on UMTS to save power. If the bandwidth is needed it will ramp up to HS(D)PA (H) or HSPA+ (H+). Some networks just have HSDPA and HSPA+ and no UMTS, therefore they will jump between H and H+ depending on network load.

Are you sure about this? First, I thought HSDPA and HSPA+ are UMTS enhancements, and at their core, are still UMTS-based. Secondly, I've not seen it indicated that H or H+ would require more power than UMTS which has not been enhanced or upgraded to the newer UMTS implementations.

At the core it is still UMTS. Hence it jumps a millisecond to UMTS if it is switching between HSPA+ and HSDPA. The UMTS 'core' is there, but not made available by my carrier to be used by my phone.
The UMTS/HSDPA power draw comparison is my experience: on HSPDA data i lose about 35-40% a night (=8h) while I do maybe 10-15% on UMTS (other provider)
