Anybody here using their G1 in Mexico? What kind of SIM card are you using? Do you live there or are you there on vacation? Prepaid SIM Card? I'm going to Mexico for two weeks in April and want to bring my G1 with me. I will be turning the data off so I just need it for calls and texts. Anyone know what kind of card and what to ask for? Telcel? Movistar? Thanks in advance.
