I don't know how to phrase my question, but I am wondering if is is possible to get some information of a computer off from an iPod that was synced to it. Basically, if I have an iPod, or other iDevices, and I synced it with the iTune program from a computer. During this sync process, is there any information of the computer that might be transferred into the iPod? If so, is there anyway to find out those "host" computer information from the iPod, by any other means? If it is possible, how to completely erase those information from an iPod? Thanks!
