When using 91 Mobile Assistant to back up an iPhone...can I back up the game saves and games in the Iphone? Or can I just back up other things such as the address book?

Games can be backed up, and you can choose what to back up, including address books, text messages, notepads, ringtones, games, etc. You can check the ones you need to back up, and then restore them to other iPhones and your own iPhone. For games, because it depends on what firmware is supported, remember that the iPhone firmware version you need to restore supports that game. Otherwise, if it does not support it, those games will not support it. The firmware version of the game cannot be used even after it is installed.
