Last year for Mother's Day I gave my Mom an iPhone 3G. It isn't set up as a phone, but basically as an iPod (since I had pulled the SIM card and she doesn't need it as a cell phone). I would like to get her a new 4th gen iPod Touch so she can FaceTime and take decent video if needed. Can I restore a backup of the iPhone 3G to the iPod Touch and keep all pertinent settings and programs and so on? I know I would need to first make sure that the iPhone is updated to the current firmware prior to running the backup in iTunes. Just wanted to see if I'd encounter any issues going to a different type of device. Thanks!
