AT&T SX56 and Special Rom Edition Rom 1.2 troubles

[TomyGunz44]

I had an AT&T SX56 phone and it worked great. I just bought another one because mine broke. I used the sim card that was in my old phone but it doesn't pick up ANY network. When I went to manually choose a network, they were all European networks. Nothing from the US was even listed. It has a somewhat different software that I am used too. When it boots up it says it is running xda-developers Special Edition ROM V1.2. Is there anything I can do to fix this all up Also, the desktop is a bit cluttered for me, is it possible to have just the standard AT&T desktop?

i think it has something todo with different bands (900 1800 1900). but don't know the exact details.
maybe try a search on band selection?

Have you tried entering bootloader mode and choosing 900/1900 from the gsm menu?

after reading this post I am wondering if you can somehow change the band that a Qtec 2020 runs on. right now mine runs on 900 usa but I'm wanting to change it to 850 usa cingular uses it and it has a much stronger signal in my area. Please let me know if there is. thanks
