I'm going to be in Mexico for vacation next week, and I was wondering if it would be worth it to get the iphone 3G down there. I know how the most expensive plan is around $77 USD and the phone would be aroudn $209 USD. Now my questions are the following: 1.Does that plan include the voice plan? 2.If not how much is the total plan voice + data? 3.How much are the cancellation fees? 4.I'm a current AT&T user with a blackjack 2 and I have the unlimited data plan. Would I be able to use the iphone I purchased from mexico once I cancel the contract with my AT&T sim? Thanks for any info.
