How do I put all my data from a previous iPhone onto an iPhone 4S through iTunes?
Today I bought the iPhone 4S, and they couldn't put all the data from my previous phone (iPhone 3GS) on it because it uses a new SIM card. I need all my data from that phone on my new phone, and the only way to do it is iTunes. I would just like to know how to do this, because I need to restore my old phone for someone else. Thanks for any advice(:
