I have a close friend that wants to buy an Iphone but doesn't want to pay $300 for it. I would like the new 3GS (who doesn't)?
We were thinking that I could sell him my 16GB 3G for $75 and he would sign up for a new contract and get the 32GB GS. I'd then pay him the difference and get the new phone.
We'd then need to switch the phone numbers so I could still use my same cell number.
What would be the best way to go about this?
I'd REALLY appreciate the advice from you quick thinkers out there!
