Well ... if you put ringtones on your iPhone, make sure you still have those files on your computer. If you put custom icons on, make sure you still have those files on your computer.
Really quite simple.![]()
true... and i believe itunes backs up who has what custom ringtone so as long as they are named the same when you put them back on, those will continue to work correctly.
but... what about other things? like apps... custom graphics... and other things like that? it would stink to have to go back through and re-customize all the stuff i've changed after upgrading.
