My wife has an iPhone 3, 8GB, that is slowly dying. My mother (who is dead) left me her iPhone, a 16GB 3GS.
How do I:
Keep all the information from the phones. My mother's phone especially has sentimental value?
Wipe the 3GS?
Transfer everything from the 3 to the 3GS?
We don't care if the phone is jail-broken or not (they are not at the moment). Both phones are on the same provider.
