I read on GSMARENA that the 8525 us version is only 850 and 1900. is that true and is there any soft hack to put 2100 (I live in Brazil and 3g with TIM is 2100 here)
I think you read that wrong.
The 8525 already supports the 2100 frequency out of the box. Thats why it works in countries like Japan.
I belive what you were reading was the US (AT&T) uses 850/1900 for its network. However the phone itself supports GSM 850 / GSM 900 / GSM 1800 / GSM 1900 / WCDMA 850 / WCDMA 1900 / WCDMA 2100
Appears to be different version for US

It says (and I copy and paste)
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 2100
HSDPA 850 / 1900 - US version
Some phones have different versions for US
Every Cingular 8525, Cingular 8500 and ATT 8525 I've ever used (Mine and friends and work) have ALL supported the 2100 MHZ band.
I even searched the ATT HTC forums and all the results I've saw showed people using their 8525 in places like Japan that uses the 2100 freq without any problems. And these were all US versions.

Was in Japan last week & had no problems using my 8525 over there.
I used mine in 2100, and HSDPA work OK
Thanks for your answer

Thats the kind of answer I like to see here. Clear and objective.
(I would take of my hat to you but then it would show my bald head)
Any idea on how to get the HSDPA to work on the Cingular 8525? I have the AT&T Tilt and used the Kaiser Tweak and works perfectly. Co-worker has the 8525 but not showing up. We work about 300 feet from a cingular tower that has HSDPA because my Tilt picks it up but not his 8525.
Is there any type of setting that must be done for this to work like I had to do the Kaiser Tweak?
Thanks,

Hi, I have an Audiovox SMT5600 but my network band is 900 MHz.
Can somebody tell me whether it is a hardware difference between SPV C500 (GSM 900 / 1800 / 1900) and Audiovox SMT5600 (GSM 850 / 1800 / 1900) or is it just the GSM Rom??? I have read the thread (http://forum.xda-developers.com/showthread.php?t=241435) which explains how to upload the QTEK rom, but it didn't work for me.
I have found the following explanation but it doesn't say whether it is hardware difference or just a different GSM rom.
"The SMT5600 is a tri-band phone that works on the 850/1800/1900MHz bands, which means it will work anywhere in the US where GSM service is available. In the US AT&T uses both the 850MHz and 1900MHz bands, as does Cingular. 1800MHz is used in Asia and somewhat in Europe, though Europe is mostly 900MHz. If you plan to travel to Europe, the SMT5600 should provide some coverage, but you might want to consider a quad band phone which adds 900MHz. The overseas versions of the SMT5600 (iMate SP3 and Orange C500) are triband world phones with 900/1800/1900 MHz coverage which means they'll work in Europe, Asia and in the US though you'll miss the 850MHz coverage used by AT&T/Cingular."
If changing a GSM Rom is the solution, where can I find the 900 MHz Rom and what is the procedure to flash it? Can I just use the Typhoon tools and perform an Emergency Flash for the GSM part or do I have to replace the complete ROM (like with mtty)?
Thanks in advance!
The radio freq's are hardware, not software to my knowlege. AT&T Cingular in the USA have moved to using the 850 MHz band for HSDPA data packets and 1900MHz for voice. Since the SMT5600 does not support HSDPA, therefore the low band is not used. If your market is 900MHz only, then your phone will not handle it. In essence you would need the European version of the iMate or Orange version. Otherwise, you are constrained to 1800 MHz.
OK, but then what about kamscam's explanation in the thread I mentioned above (http://forum.xda-developers.com/showthread.php?t=241435)? He claims that flashing the phone with the QTEK Rom will do the trick.

I have the iMate 2.4.33.11 ROM if you want to try it. I believe it is WM2003 OEM Rom for the SP3 (Typhoon).
If the claim is true that he changed an 850 MHz phone to 900 MHz and it worked, then this would seem to indicate that the phone may be Quadband but the Radio ROM only operates as Triband with the 1800/1900 always on and the 850/900 as selectable. This may be a possibility, but I still have my doubts. I still believe there is a different hardware radio for the 850 MHz and 900 MHz models.
http://rapidshare.com/files/61129896/SP3_WWE_2.4.33.11.zip
There is hardware difference in C500 and STM5600 which runs on 850. Difference is in switchplexer which in European models filters 900 and 1800/1900 MHz (Murata HA 165) and in STM 5600 (Audiovox) filters 850 and 1800/1900 MHz (Murata HA 216AW). You have to change switchplexer on the board if you want 900 MHz on Audiovox
OK, I guess this concludes the story. I have actually suceeded in flashing a different GSM Rom (Qtek) but the phone still couldn't pick up the signal.
Thanks raskell and typakkk and everybody else for help!
Hi .. I was searching the forum because I want to purchase an HTC HD2 T9193 which, I know, has the 850 - 2100 Mhz band. But I found on the net a vendor who offers the HTC HD2 850 - 1900 Mhz band, is this right ?
On the other hand, if there is not such HD2 with 850 - 1900 Mhz band, the one with the 850 - 2100 band will pick up 3G in Canada ?
That model (850 / 1900) was supposed to come out (for AT&T most probably), but it has since been cancelled.
I'd be careful if I were you. You can find more info about it here
The Telstra model (T9193) supports 850 / 2100 MHz like you said. You'll need to check with your service provider if they support 850.

Yes. You'll need to check if ATT supports the 850mhz band IN YOUR AREA.
I'm in a North Shore Suburb of Chicago area and have excellent reception with my T9193 in the area. There are 3 dead zones I've found so far that repeatedly drops calls using the HD2's 850mhz band exclusively. Other unlocked phones I've previously owned that used the 1900mhz band exclusively did NOT drop calls in these areas however. Other than that, reception has been great. It's been reported that ATT is "supposedly" moving their entire network to the 850mhz band exclusively by end of 2010. I'm doubtful they are on target for this date given the number of cities still without any 850mhz support.
T9193
Hi guys ...thanks for your responses. Well, I know that the most important service providers in Canada (Rogers, Telus, Fido) transmit 3G in the 850 - 1900 mhz band. I suppose I will not have problems whether I use the T9193
Hi,
I'm from Switzerland and I've to buy a new phone for my father that lives in argentina... the problem is that here the 3g frequencies standard for phones are 900 & 2100...
What are in argentina, I've seen that are 850 and 1900....
The only phone I've found for acceptable price is the samsung galaxy S that has 900/1900/2100 (no 850mhz!!!)... will this phone work???
last question is... if i've only quadband gsm and 900/2100 3g can I use internet also with slow velocity?
help please
nothing for now?
Motorola Defy ?
3G Network HSDPA 900 / 2100
HSDPA 1700 / 2100 or HSDPA 850 / 1900
Have a look at GSMArena Phone Finder - here you can tick the frequencies you like. The only phones that offer quadband UMTS for now are latest Nokias (for example C7, E6, X3-02) and Samsung Galaxy SII. If you buy a quadband GSM and 900/2100 UMTS phone you would be able to use only GSM in Argentina.
So I am keeping my Nexus 4, however I am in the market for a a phone for my wife. It has to work with T-Mobile and I would love to find her a HSPA+ compatible phone, however i am really confused on how to figure this out.
For example I am looking at this phone at GSMArena:
Sony Xperia T and they say these are the bandz:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100
How do I know it will work with T-Mobile's HSPA+?
Any help will be appreciated.

Thanks bud, but that doesnt answer my question, I dont need to know what coverage is in my area, but more what phone is capable of using T-Mobile's HSPA+
Yes it will. T-Mobile used 1700 and 2100 for HSDPA.

Thanks EL Daddy! So if a phone lists those bands 1700/2100 that means it'll work with HSPA?
I ask because I am also looking at this phone the Xperia S and those bands are :
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100 - LT26i

That one will probably not work as I believe you need both the 1700 & 2100 to work ( up & downlink connection).

3G or UMTS is as follows;
2100 refers to Band I / IMT and is used in Europe and Asia
1900 refers to Band II / PCS and is used by AT&T in cities, and by T-Mobile (1900 migration).
1700 refers to Band IV / AWS and is used by T-Mobile (most HSPA service is still here).
850 refers to Band V / CLR and is used by AT&T in rural areas.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
T-Mobile is slowly moving HSPA from 1700 to 1900 to support unlocked iPhones and free up 1700 for LTE deployment.
I would look for a phone that supports both (1700 now, 1900 future) or it may have a short life span.

Awesome! I see now, so in order for the phone to work on HSPA it needs both 1700/2100 bandz. AAHHHHHH SWEET! Thanks guys I made sure to hit the thanks button on both of you!

Nexus 4 works great on T-mobiles HSPA+ . I regularly get 20.8 mbps down/2.5 mbps up.. and this is in a 1700/2100 mhz AWS area .. PDX area has not been refarmed to 1900mhz yet - and Nexus 4 supports both 1900 mhz HSPA+ and AWS HSPA+ - so no worries.

Just to clear up one thing. T-Mobile often refers to 2100 as the Download Frequency of AWS (Band IV), while most hardware manufactures reference 2100 as IMT (Band I). See column 2 in the wikipedia link I posted earlier.
I get both bands here in NYC (mostly AWS) and the speed is about the same on both (20 Mbps / 2.5 Mbps), but ping results are quite a bit lower on PCS.

I was thinking about buying me a open line LG Optimus G2 then bringing it to japan, and give it as a gift. Ive been doing some research on the net, and it says that Japan doesnt support of use GSM frequency band, because they are not using 2G or something? Can someone please enlight me or explain this to me. How this things work, because i had already tried, and called the site here in norway that who are selling it. They told that it supposed to work but, after i have done my search on my own, i really doubt that what he told me. lol
So can somebody please or tell or can confirm to me that working or not?
These are the frequency band of LG Optimus G2: 2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 900 / 1800 / 2100 / 2600 / 850
Thank you for your answer
