I am on a family plan with ATT and my phone broke so I'm in the market for a new one. Someone else in the plan is eligible for an upgrade and they told me to use theirs to get a new phone, and then just switch out the sim cards. I want to get the iPhone 4, but currently own a (busted) iPhone 3GS which operates a regular sim, instead of the MicroSim I would need for iPhone 4. How do I go about getting a new MicroSim for my phone number that I can install into the iPhone 4?
