I have the iphone 3G and wife is getting i4. How do I transfer her contacts from her previous phone to i4. is it just taking the sim out of the old phone and putting it in the i4. Or its a different process? How will I sync her phone. I have an itunes account. Will I have to make a new account for her. Can we buy 1 app and share it in 2 phones. if this is possible then how? Should the app be downloaded in itunes and then synced, or it does not matter how we download the app itunes or either phone.
