I am sure there is an easier way, but I am stuck. I upgraded my wife's iPhone 2G to a 3GS. She backed up, on her iBook (I know she needs a new laptop) plugged in the new iPhone, and she has been up and running ever since. I have a MacBook with which I sync my own 3GS. I want to use the old iPhone as an ipod touch, with my apps, music, etc. It won't let me erase an connect to my iTunes. 1. Should I restore? Will this option jack up my syncing of my 3GS? 2. Should I erase and they try to sync with my MacBook? Please Advise. Aloha, FUDGE!
