Help please! Can a Wallaby work on Cingular Wireless, USA?

[freudr]

I've tried to get my beloved Wallaby working now on two USA networks, T-Mobile and Cingular to no avail. I bought this new as an O2 XDA 1 in England while I was living there and miss using it so bad.

I've installed the full xda developers kit. It looks good and very functional, but I've never been able to get the phone to turn on with my new SIM from Cingular or my old one from T-Mobile.

I've tried the bandwith switcher and no dice, not on any of the frequencies. I have the model number 10A1 which is listed at only 900/1800 but Cingular runs on 900/1900 I've been told. Wouldn't it just use 900?

I'm so lost and confused. A little help anyone?

Thanks

According to a friend of mine who inserted Cingular SIM to his unlocked T-mobile pocket pc phone and it worked fine.

I can confirm:

Yes, Unlocked Wallaby + Cingular SIM card = GSM and GPRS connectivity. Works fine, except recpetion is retivively crap in my area (compared to Motorola RAZR, the Wallaby frankly sucks for reception.

Any thought about a RSU upgrade that might help? Phone states it is on 6.18.00

You need the 10B1 board for the USA since 1900 is used in the US
