As others have said, look at the sticker inside the battery compartment. It's the only way to tell, there is no software-based way: as discussed on this list earlier, with the standard /gsm/com/rfcap setting from Om the modem has no knowledge of which version it is, believing itself to be quad-band instead. > Can I just use any network in the USA, In the part of USA where I operate (Southern CA) there are only two GSM networks: 310260 (current marketing name "T-Mobile USA", used to be VoiceStream) and 310410 (current marketing name "AT&T", used to be Cingular - the decoding table in our GSM firmwares still calls it "Cingular", BTW). All of my current/recent experience is with T-Mobile; the last time I used the other network was some 11-12 y ago, back when they were Cingular. If you come to Southern California, I can confirm that you can go to any T-Mobile retail store, buy a SIM card, plug it into your GTA02 (mine is exactly like yours), and it will work. (For me it works with *both* the original factory IMEI and the one I made up for testing. :) If you decide to try the other network (AT&T), you'll be venturing into so-far-untested territory, and contributing new knowledge. :) > and it will just register with the 1900MHz band Yup, that's the band I've been using here for all my cellphone-using life. I have yet to use a phone with 850 MHz capability - this "secondary" USA band is a relatively recent addition (a spectrum reallocation from AMPS, it seems), and back in 2003 when I got my first Mot V66 (the subsequent ones have been from ebay), all phones officially sold in USA with carrier branding were 1900 MHz only or 900/1800/1900 MHz "world phones" like that Mot V66! Again, this is with a T-Mobile SIM card, connecting to T-Mobile base stations in the 1900 MHz band - no idea what the picture looks like for AT&T.
