My daughter is going to spend the next school year (August 2011 to June 2012) in Memphis, TN as an exchange student from Switzerland. She'd very much like to use her iPhone during her stay in the United States.
What are her options for getting prepaid talk, text and data services without also having to buy a new phone? I realize that she'll be limited to AT&T and T-Mobile because of the GSM network.
As far as I've read, T-Mobile SIM cards only work on T-Mobile branded phones, so is AT&T her only option there?
