Well, I'll be definitely using GSM phones, both the one I'll take and the one I plan to buy there eventually (yes, I am very hopeful the Harmattan phone will become available while I'm there! ). I don't care much about the connection speed, EDGE is perfect, but the locking thing would certainly blow!...

I will check out the frequencies my phone supports. So AT&T and T-Mo are really the only two with GSM networks, right?
