Backing Up Purchases on Different PC Without Syncing Devices
Apologies in advance if this question has been asked before, and if it has you can simply link me in the right direction.
My iPad (and iPod Touch for that matter) were both synced to my laptop. I've since had an incident where my user profile wont load on my PC. I've purchased apps on the iPad since and would like to back this stuff up on a different computer WITHOUT syncing or altering anything that is on my iPad (and iPod Touch).
What steps do I need to take to ensure that all purchases made on my devices are backed up without syncing my devices to this other computer. Additionally, will I be able to update to iOS 4.3 when it comes out without impacting what I have on my devices?
If my question isnt quite clear enough, please let me know and I can elaborate.
Thanks in advance and apologies if this has been addressed 744 times already.
