Hi guys, I've been having some problems with my old 2G iPhone so my insurance are replacing it with a brand new 3G iPhone. I have to hand in my old phone at the same time as I receive the new one so just want to make doubley sure I back it up properly before handing it over. Is it as simple as backing up the old phone with iTunes and restoring it onto the new phone? Is there anything that isn't copied? Any way to check the backup because once I hand the phone over there's no going back? I assume it would be wise to erase all the data on my old phone - how do I do this?
