O2 xda tri-band phone

[Anonymous]

Hi there!

I live in France and I go often to California. I always had a spare GSM phone tri-band for the US and Canada.

Last March, I bought an O2 xda in Australia, in a Telstra shop, thinking it was a bi-band phone. Back in Paris, I found this site and learned how to access tho the GSM menu (I had found myself how to access to the Wallaby bootloader 5.17, but I didn't press any other key after the message "GSM OK").

I've just come back from San Diego and while I was there I changed the band to "1900"... and the xda worked perfect!!! Back in Paris, I've switched back to 900/1800 and I'm using again the European networks :D

Thank you!

What?

We've always believed the phone had physically different hardware for 900/1800 and 900/1900 operation, and I seem to remember seeing negative test results.

The O2 XDA you bought for sure is 900/1800 and not 900/1900 ? (remember: it would work in Paris if your provider is on 900).

Let's all follow up on this one carefully. For now, let us not imediately assume the units are tri-band.

I have heard that O2 are likely to release a tri-band version with 64Mb internal RAM.

This will be called the XDA 64i and is likely to sport Bluetooth also.

Any further news on this appreciated.

Hey ArtZ

Let us know if your carrier is a 1800 Mhz Carrier.

If the XDA is triband that would be absolutly awesome.
:lol:

Hey guys
Now this is VERY IMPORTANT NEWS
Can we have more info and more confirmation (more experience in this ?)

My carrier, SFR is a 900Mhz carrier. In fact SFR (Vodafone) and Orange (France Telecom) use the 900 Mhz but in some places to avoid network congestion they use also 1800 Mhz band. BOUYGTEL (Bouygues Telecom) uses only the 1800 Mhz band.

I've just made a test. I have configured the phone as 1800 Mhz only. I couldn't find my carrier SFR. Then I tried to select manually the network and I only could see BOUYGTEL (1800 Mhz). I have tried in the past my XDA with a BOUYGTEL car also and it works fine. So my phone is configured for 900/1800 carriers.

After this, I changed network again (1900 Mhz) in Wallaby bootloader. Then I cannot see any carrier. In California I was connected to Pacific Bell using the 1900 setting.

As I told you before, I bought my xda in Australia last March with the latest firmware. It's a 64 Mb internal RAM

I'll be back in California (on vacation) on June 30th for 10 days. If you wanna make tests...

Hi ArtZ

This sounds great.

Sorry to bother you, but can you tell us please which firmware U are using for the PDA and for the phone?

Thanx! :idea: :o

PS: for me it will be end of the year, so this is a long time... :oops:

I forgot to tell you the versions installed (I haven't updated them yet) are:

RUU 3.14.17
RSU 4.17

I don't think my xda is the XDA 64i. It has no Bluetooth. I think the 64Mb version just came out in Australia when I was there in March. There're are maybe harware changes with the 32Mb version and the 64Mb is a tri-band.

Hope that helps.

It's me again, sorry to bother you.

I run all the tests from the Wallaby bootloader. The version I have is GPRS 4

It will be interesting to check if you have new versions over there.

I found out that the xda has just arrived in France by Bouygues. I will try to get more information about it but I think it's the same model I have. Bouygues doesn't say if the HTC iPDA is a bi-band or a tri-band telephone

Hi,

My version is GPRS 4.1332s54 What ever this means? :shock:

[Anonymous]

HI Artz,

Great news you have given. Can you please clarify step by step how you changed the network frequency of the phone?

Thanks

Look on the back of the device, the part number will tell you if it is a 1900 unit or not.

PW10A1 is the 900/1800
PW10B1 is the 900/1900

The Bootloader is identical. CE is different as the option to chose the 1900 band (which you have to do manually) is only in 1900 CE versions.

The hardware is different between the two versions. The radio circuits and filters are different. You "could" switch the radio of a 1800 unit to try and do 1900, but your coverage would be extreemly poor as the 1800 filter is actually filtering out half of the 1900 band.

Your 1900 operator will NOT like you.

superblurr, lazy boy! :roll:

All information is here, in xda-developers.com. Just take a look at this page :P

http://www.xda-developers.com/bootloader/

It will be nice if someone from the States comes to Europe and try his xda here. And if you go to the States (or Canada) take your xda with you. It's the only way to find out if there're different models

My version is:
GPRS 4.1332s54 (as silversurfer)
RUU: 3.14.17
RSU: 4.17
Model: PW10A1

Anybody got a spare XDA they want to send to the US for testing for a few days? It usually only costs me about $12 to ship something that size to Europe, and takes about 5 days. I would imagine it to be similar the other way.

[john]

this sounds great! i own a 900/1900 from t-mobile. is it then possible to change my 1900 into a 1800 mhz? because i get sometimes no network signal. i live in europe, and need the 900/1800...
Can anyone explain please?

[chasl]

I bought a US T-Mobile (PW10B1) and did a SER1.2 flash, it went flawless....Thanks to the xda-developer team and Jef, you guys are the best!! The only bug I notice so far is Phonext which is not working at all. I am using the phone in Singapore using the 900/1800 band and it works perfectly. I've been reading about TMO2003 in this forum, my question is does this upgrade come with bandswitch.exe, this feature is very essential to me as I travel very extensively btw Asia, Europe and the US. By the way does anybody know what is a .rar and .nbf file? :?:

[rustek]

.rar files are compressed files like zip.

download a freeware prog called winrar and you'll be all set.

[rustek]

The UK will see the new XDA from O2 by the end of this year.

It's now known as the XDA II

it will be 64Mb, tri-band and bluetooth plus a built in camera and enhancements to the wi-fi link etc.

[chasl]

Thanks Rustek. How about .nbf flies? Is TMO2003 for PPC2003 only? what's the diff. compared to SER1.2?
