I am giving my old iPhone 3Gs to my son. It was configured to my Exchange server. I did a remote wipe successfully. I then upgraded to the current OS 4.2.1. When the phone boots up, it shows me a picture of a USB cord and asks to be connected to iTunes to activate (why?) which I do successfully. It then looks to connect to my WiFi for which I enter the WEP key and it conects. Here's the problem: I set it up to connect to my exchange server for my son's email account. As soon as I configure this, the phone shuts off, re-boots and takes about 20 minutes to come up. I then get the picture of the USB cord all over again. Very frustrating.
Also, how do I specifically perform a backup via iTunes instead of a sync. When I connect it to my laptop, iTunes syncs it to the apps library and then all these apps I dont want on his phone get loaded. Everytime I conect it, the phone syncs, which takes up needless time. I want to be able to control when I want it to sync, versus when I want it to back up. How do I do this?
