Band switch 900-1800 to 1900 Mhz.

[gui]

Hi, I have an O2 XDA from australia and I update the rom with de SE 1,2
Rom version:3.17.03 ENG
Radio version: 4.17
Protocol: 32554
I live in Argentina and we have here the 1900 Mhz Band. I didn't find the way to have gsm signal, and I think that I have the incorrect radio version to work in america.
Someone Knows what can I do?
I will appreciate your help.

Thanks, and please be patient with my english.

Of course, I'm sure!
GSM 900/1800 phone cannot work on GSM 1900 network!
the bootloader is written for both GSM 900/1800 and GSM 900/1900 phone. you may see something GSM 1900 test on PW10A1 pone , but it does not work on GSM 1900 network.
I have both XDA GSM 900/1800 (PW10A1) phone and GSM 900/1900 (PW10B1). I'm in Canada, only GSM 1900 is available. PW10A1 not working here!
