I'm undecided between replacing my iPhone 3GS with an iPhone 4S or a Galaxy S3, but that's by-the-by. I'm looking at either totally formatting my HD and/or replacing it with a new, bigger HD. It's likely though that i'll have replaced the phone before i get a new HD. What i want is to backup the iPhone backup & put it back in whatever directory it's supposed to be in once Windows has been fresdhly installed again. This is so that if i get a 4S or even if i get an S3 but replace it with an iPhone in the future, then i can restore from the backup & have all my old settings, text messages, apps etc etc on the new iPhone. Hopefully what i've said has made sense. If so, how do you do it? Thanks.
