If I acquire an iPhone, can I recover it (in addition to application data) from an iPod Touch backup?
As I remember, when you first sync your iphone, you will certainly be motivated to do so, so of course!
I would certainly advise you to do a sync on your ipod prior to syncing the iphone.
Seems viable. The last blog post on this site claims a person obtained it to function. Do an actual backup (not simply sync ) however.
