So from what I know,
MyTouch3G = MSM7201A, 192 MB RAM, TriBand 3G (900/1700/2100)
HTC Magic = MSM7200A, 288 MB RAM, DualBand 3G (1700/2100 or 900/2100)
I've done some reading and realized that due to patenting issues with BroadCom, the 7201A was released, limiting video recording to 320x240.
So theoretically, If I have a Mytouch, it can be downgraded to look for only 2 3G Bands and an HTC Magic can be upgraded to look for 3 3G bands.
Both CPUs are Triband 3G Capable. Is there any way to load a rom that will look for 3Frequency bands on the HTC Magic? I am just trying to understand why they are crippling a phone thats Triband capable to only be Dualband 3G.
Even with the HTC Hero, they have gone wrong and done the same stupid crap. Can anyone explain this to me. Am I missing something here?
Why does my mytouch have so much less ram? That's completely devastating

The HTC Magic also comes in the 850/1900 3g variety too!

I think it is a hardware issue rather than a software one to change 3g bands.
I am not convinced... The Chipset supports it...
Anyone wanna take a stab at this? Maybe one of the developers?
Anyone else care to shed any insight to this??
I would love to have a 32a model that supports 1700/2100hsdpa bands, besides the new mt3g limited edtion....
What you are describing is the difference between 32A (288Mb) and 32B (192Mb) HTC Magic. myTouch3G is just a T-Mobile branding, Vodafone still call the 32B "HTC Magic" in their foreign markets like UK, Norway and Australia.
In my experience with other non-phone-handset 3G hardware you are probably right. Radio chipsets usually electronically support all bands, and are locked down to regional frequencies by firmware or software settings. The 3G Cisco routers I work with can run on any frequency they can find which the hardware supports.
Computer 802.11a/b/g WiFi controllers work in the same way, there are frequencies you can/can't use in USA/Japan/EU/Australia but if you get the right software (like DD-WRT) you can use them.
That is, however, usually against the local telecommunications law. I'm not sure if the same legalities apply to mobile phones. You could potentially interfere with a registered emergency channel which isn't a legal situation I'd like to be in.
I am unsure if the MSM7201A and MSM7200A actually have a different radio chip, I've never looked into it. Isn't the current "latest" radio for 32A and 32B a different version? 22.x.x.x versus 33.x.x.x or similar? That would imply a different physical chip.
hi every one im thinking about buying a tmous htc hd 2 cause of the 1gb rom 576 mb ram , im just wandering if the phone will work in australia 3g , vodafone , i found out download band for voda is 2100 and upload 900
can some one shed any light on this should i buy the tmous htc hd 2 or t8585
thanks in advance
The TMOUS HD2 is actually the least useful of the three varieties to you (TMOUS, Telstra, European/international) - I use a TMOUS in New Zealand, and the gist of it is that it will work absolutely fine once unlocked, but it has a useless second 3G frequency - you'll only be able to use 2100, since the TMOUS uses 1700 as (I think) rather than the more standard 900.
The Telstra variety has 2100/850, and the European HD2 has 2100/900.
So, if you just want the extra ROM space, go for the TMOUS. But if you want better 3G coverage, it depends whether you want Voda or Telstra as a service provider.

No, The T-Mo US HD2 won't work on those 3g bands. You want the t8585.
Or the 9193. which is the AU model that will work with ATT USA 850 band 3g
thanks for the reply whats the differnece in having 1gb rom

I'm very surprised to hear that your 9193 locks onto an H or 3G icon with Vodafone. EDGE, sure, but that's 2.5G data, not 3G.
The 9193 supports 3G/HSDPA on 850 and 1900MHz
The 8585 supports 3G/HSDPA on 900 and 2100MHz
Everything I've read about Vodafone points to them using 900 & 2100MHz bands for 3G/HSDPA.
band
i am using 900 2100
i used a cab to add more bands
BAAAAHAHAHAHAHAHAHA!! ROFLMAO
You're an idiot, stop posting misinformation.
If you use Telstra then you need the t9193 model but if you use any other provider you will need the t8585 model to be able to access the full 3G service, I could be wrong but that's what caught me out.
I am on Vodafone and I have the T8585 with H E 3G & G bands via 900/2100.
gamecore is correct T9193 for Telstra, and T8585 for others eg Vodafone etc...
ok i am new to this but can someone tell me what's the different between
the
T8585 and the T9193 (i know that the T8585 is the one with the 512 rom) so is the T9193 the telstra verson of the HD2?
i am going to america next month and just to make things clear
(i am on optus)
if i want to buy a HD2 with the 1GB ROM it won't work in Aus ?
so should i buy the normal verson of the phone (T8585)?
if i just want to use the phone for call,text,mms (no internet browsing) can i get the 1GB one ? or would i still get the T8585?
so if i want the phone to be able to use the internet(not wifi) "on the go" and check e-mail i will need to get the T8585 right ? ( the one with less rom?)

STHD,
A brief lesson in mobile phone protocols, and which model supports what:
T8585 & T9193
Worldwide
GSM, 850/900/1800/2100MHz
GPRS, 850/900/1800/2100MHz
EDGE, 850/900/1800/2100MHz
T8585
Australia (Voda, Optus), Europe, Asia
3G/UMTS, 900/2100MHz
HSDPA, 900/2100MHz
T9193
Telstra AU, USA (most), Japan (I think)
3G/UMTS, 850/1900MHz
HSDPA, 850/1900MHz
So,
Both the T8585 & T9193 can use the following services worldwide, on any carrier that uses the GSM (NOT CDMA!) mobile network:
* Calls
* SMS
* MMS, assuming you have some sort of data plan supporting GPRS or better.
* Mobile web & email, but only at GPRS (data rates of 56-114 kbit/s) or EDGE speeds (up to 236.8 kbit/s).
The T9193 supports 3G/HSDPA on 850 and 1900MHz - Telstra & most US carriers use these frequencies for 3G data.
The 8585 supports 3G/HSDPA on 900 and 2100MHz - Most European, Asian and all other Australian providers use these frequencies for 3G data.
See http://en.wikipedia.org/wiki/Template:Mobile_telecommunications_standards for a heirachical view of the technologies.
Three key points here:
1) You can't (AFAIK) buy the T8585 model from a network provider in the USA. They will all be T9193 models.
2) If you're *visiting* the USA, and indend to to use the phone on Optus when you return, buy the T8585 model from somewhere in Asia or Europe (http://Handtec.co.uk is my personal recommendation). You can still use the phone when you go to the USA for calls, sms, and gprs & edge data, and get full 3G/HSDPA speeds when you come home to Optus.
3) Ignore the 1GB Flash ROM on T9193 model. The T8585 comes with an 8GB SD card - just install all your apps on the card. This has the additional benefit that you don't need to re-install every time you flash another ROM.
Make sense?
Phrak
So basically you need the T8585 for Optus.
If you get the T9193 for optus network you can do everything that the T8585 does but you wont be able to use 3G it will only be 2G or slower for web and emails on your phone.
ok thanks Phark that really help me out working out the issues
just to point something out from Phark post
T8585 Should be T9193/T-mobile verson
Telstra AU, USA (most), Japan (I think)
3G/UMTS, 850/1900MHz
HSDPA, 850/1900MHz
not picking on you (Phark) but just want to make sure everyone gets it or else it will be confusing (am i right?lol)
but another thing is that on the htc website it says that the aus verson (T9193) of hd2 uses "Australia: 850/2100 MHz" i donno if the info is wrong or what...
Also T-mobile and [HD2 US(from PDAdb)comming soon] have 576Mib of Ram which is 100 something more then T8585
So i guess i will get the T8585(Will get that in HK)
Haha and i really like how Phark quote *visiting* USA...but i am really going there Haha
Thanks again Phark and also thanks gamecore

Unsure about that one, sorry. Everything I've read (up 'till now!) suggests that the T9193 was 850/1900 - *Do* take HTC's word over mine though, you can always claim false advertising against them ;-)

The T8585 *does* have 576MB of RAM, enabled via most ROM Chefs. I'm unsure of the technical changes to enable this, but I've just (double) checked my T8585 HD2 from HK, and it says: "RAM: 576MB; Flash Size: 512MB"

hd2 telstra t9193 - Vodafone Australia
Hey Phrak,
This is the cab i used for geting the extra bands
http://htcpedia.com/forum/showpost.php?p=57342&postcount=6
is this the correct band for Vodafone Australia?
UMTS(900+2100)+GSM(900+1800)
If not what should it say???
Is there a hardware difference that the t9193 will not have the correct data connection? Or is it just software?
Interesting CAB - I've just found the same software built into the latest ENERGY ROM I've flashed to my Leo.
More research is needed methinks. I'm more than prepared to be proven wrong on the T9193 supported bands.
I just got off the phone with the repair guys at HTC and they assured me that the HD2 from USA T-mobile is in fact the T8585. All parts are compatible.
I know alot of people are confused when trying to fix parts. so remember
T8585 = USA HD2 T-Mobile
isn't the T8585 the EU version?
T8585 is NOT the US T-mobile version it is the international one

Yeah, that's why Otterbox makes different size cases for the US version and European version. Cause they're the same. Maybe the repair guy was telling you whatever he wanted to because he didn't really know and didn't want to take the time to look up the facts for you.
The TMOUS HD2 is T8585 and the European HD2 is also the T8585. both are them are the same model #.

all the sites that sell the T8585 state that it is not compatable with t-mobile 3G
because it is
size:
120.5 x 67 x 11 mm
157g
3G
HSDPA 900 / 2100
HSDPA 850 / 2100 - Australian Version (compatable with AT&T)
the T-mobile HD2 is known as the T-mobile HD2, not the T8585
Size:
122 x 67 x 11 mm
157g
3G:
1700/2100 bands- not compatable with AT&T and some European carriers who use 900 band
Good day guys. I need your help. I want to replace my motherboard because processor wont work properly(freezes, green screens etc.). So i want to know, is there any difference between international ver. of hd2 motherboard and T-mobile version, and could I buy T-mobile motherboard and replace it in my international hd2. If it is possible, so i want to buy this motherboard
cgi.ebay.com/HTC-HD2-Unlocked-100-Working-motherboard-only-/230603065490?pt=Cell_Phones&hash=item35b1038892
(and if you will find some analog, please let me know)
Thank you for helping.
I believe the T-Mobile motherboard/main board is slightly larger in size to the international HD2 do to the more rom space and things on the T-Mobile version. So you can probably interchange a international main board with a T-Mobile HD2n but I don't know about a T-Mobile main board in a international HD2 as the actual outer casing is smaller than the T-Mobile.
Thank you for fast answer T-Macgnolia. I was thinking about it(i mean different sizes etc) but may be it's still possible, i mean ... its probably my last chance, so if you are don't know, for sure there is someone else, who tried this and know that it works, or know for certain that it's impossible. But anyway i need to replace it, doesn't matter t-mobile or international ver. of mainboard. I just couldn't find international ver. yet. So guys if you have any links of selling this motherboard, please let me know(doesnt matter where, may be in europe too).
I've got the same problem and I've done some research on it, but I'm still not really sure whether or not the international motherboard can be replaced by the T-Mobile one.
Here's what I found out:
(quotes from another web-site)
"Memory:
T-Mobile HD2: 576MB RAM, 1GB ROM
HTC HD2: 448MB RAM, 512MB ROM
The T-Mobile HD2 has a 128MB RAM advantage over the HTC HD2 if we are talking about the stock specs. Latest developments demonstrated that the International HD2 has the same amount of physical RAM, but the additional 128MB has been hidden and thus unavailable, but unlocked via applying custom ROMs.
As far as ROM is concerned, the T-Mobile HD2 has twice as much storage memory than the international HD2, mainly because of the customizations the operator version has (not to mention the Entertainment package including Barnes & Noble eReader, Blockbuster on Demand - Blockbuster’s first-ever video download application on a smartphone, MobiTV, Gogo Inflight Internet Services - six month trial for inflight wifi services on over 2,500 daily U.S. flights and Slacker Radio)."
"Bands:
T-Mobile HD2: WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz, GSM: 850/900/1800/1900 MHz.
HTC HD2: Europe: HSPA/WCDMA: 900/2100 MHz, GSM: 850/900/1800/1900 MHz. Asia Pacific: HSPA/WCDMA: 900/2100 MHz, GSM: 850/900/1800/1900 MHz.
Main difference here is the one and only vital one: the T-Mobile HD2 supports the 1700 MHz band not supported by the International HD2. Additionally, we've posted about how to get AT&T 3G speeds with imported Telstra HD2 from Australia, which supports UMTS 850Mhz."
But still there's one thing that makes me still hope the international version can run with the T-Mobile MB: regardless the fact that the T-Mobile version is 1.5mm taller they both weight 157 grams and plus to that, I think it would be smart move to manufacture the other phone parts in such a way that they would fit both versions.
I hope I'm gonna get some answers from a couple of GSM services I've contacted lately and get back to you with the answers. Brace yourself! =]

T-Mobile is strange about sizes and custom phone cases. My previous phone was a TP2, and the T-Mobile version had a completely different case and front, for no reason that I could see except looks.
So, I got some answers. All of them conclude the fact that it's impossible to use a T-Mobile MB on an international version!
Reasons why:
- the T-Mobile motherboard is longer, so you'll have to rethink how to attach the motherboard to the housing;
- on the international version the flex cables and all the other cables are soldered to the motherboard, while on the T-Mobile version they're connected through various connectors.
Bad news, bad news...well all you can do now is hope to find a used and working motherboard, buy a phone with a broken screen or something else (those cost as much as a used MB) or sell the phone for parts...
Good luck! I'm gonna need it too ;]
Hey spnk! Thank you so much for help and your great research!
I had a thoughts like that, but still got a hope ^_^. However now the story has ended.
I've bought a new one from taobao, costs much cheaper than on ebay(ofcourse it's chinese assembled, but it says "made in taiwan" , so i dont know anything about "makers", but it's well built).
I left old, "broken" one for parts. Who knows, may be it will be usefull.
I hope that you've solved problem with your's.
Best wishes.
