can the CINGULAR 8525 use HSDPA 2100

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,

X1 not working with USA 3G ?

X1 has -
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
ATT - is
850/1900
why cant i connect to 3G here in the US ?

You may have a X1i. Which has 3G bands 900/1900/2100 and you live in an area with 850MHz 3G.

Since the X1a, which is the model with the specs you posted, hasn't been released yet (apparently ships today according to Sony Style), I doubt you have the right Model. You have the X1i.

No i have
GSM 1900-850 and UMTS 1900 850

says so in my settings.. but i dunno

it reads X1
not X1i
and has an FCC ID under the battery where the S/N is

Did you get it from US? Or overseas? Europe Asia?
If not from US, then its X1i version.
And I think the X1a was just released today, right?

Sorry, but you probably have the X1i, unless you got a very lucky prerelease of the X1a which has not shipped yet. There are numerous posts that are confirming that there is only 1900 on the X1i and not 850. This means that it will work in some 3g areas, but not all.
The X1i lists all of the bands in the settings menu despite the above info. It's a bit misleading, but even though the software lists both, it doesn't always mean that the hardware supports it.

Hi Uber,
You have an X1 also known as X1i
The UMTS is 900/1900/2100
Europe uses UMTS 2100 so you select setting 1= 1900/2100
USA AT&T uses UMTS 1900 in some areas, while in other areas it's 850
The reason your Xperia also have setting 2 as UMTS 850/1900
is for when you travel to a UMTS 1900 country like parts of USA
But since your device doesn't have UMTS 850
it won't work in a country with UMTS 850 like
Australia, Canada and some areas of USA.
Where in USA are you located?

im using AT&T here in the los angeles area. i got 3G no problem indoors as well as out. so hope this helps others. also...you might have to disable the hsdpa/hsupa in the advanced network. if you dont, you get the "H" symbol...which i heard is a little bit slower than 3G. hope this helps

Hi vicsingh71
Sorry to tell you but that is wrong as 3G is a max speed of 384kbps whilst HSDPA is max speed of up to 7.2mbps for download and i think HSUPA is 2mbs for uploading. Anyway super fast Data also called 3.5G is what these two are and they are both much faster and a better service then just 3G.
Marc

i also have a x1i purchased in the uk. i live in Los angeles and the 3g works perfect! The only reason sony made the x1a is to be able to sell it in the us. the x1i uses a qualcomm prossesor that is in litigation with nokia here in the us, so it cannot be sold here. that is why the downgraded the chip for the x1a. my advice is to get the x1i

HTC HD2 T9193 850 - 1900 Mhz ?????

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

[Q/SOLVED] What to Use in Canada?

Hey,
I like the Desire Z, I use rogers is this going to be possible?
I currently run t-mobile touch pro2, but in my city they are just upgrading to 3g unlike bigger cities liek Toronto already have it.
# GSM/GPRS/EDGE on the 850 and 1900 MHz bands (Also known as 2G GSM, or 2.5G in the case of EDGE)
# UMTS/HSPA on the 850 and 1900 MHz bands (Also known as 3G GSM)

According to this article...
Bell is going to launch the Desire Z it will have the bands you need for 100% 3G compatibility, since I'm on ATT here in the US, I might have to pick one up too.

Thanks,
that's definetely what I was after... i get confused sometimes...
cheers

Is the Qualcomm chip on the new TMo SGS2 worth it than the Exynos siblings?

Just as the question say:
TMo SGS2 Qualcomm vs. SGS2 siblings (AT&T/Sprint) Exynos... Is it worth it?
Found this on the other forum that I found interesting, and could be a debatable topic:
The AWS (1700) bands are supported only by a handful of carriers. It doesn't exist at all in Europe and Asia. There's little reason for manufacturers to include it on their global phones as so few people use it. It's the reason the T-Mobile SGS2 has a Qualcomm chip instead of Exynos like the rest of them. After the merger, it won't even exist in the U.S. any longer as AT&T plans on using it (1700) for LTE. If you want versatility and the ability to use unlocked phones, change to AT&T.
^Even international version doesn't support T-Mobile 3g/4g (HSPA+) network.. Not many phones support their network. Or maybe it will.. but not everywhere
