Hi, I want to update my iPod Touch to iOS 4.2.1 and jailbreak it, but I want to back up my apps and everything. Usually, I just sync everything into iTunes (transfer purchases), but recently I reformatted my computer and now it won't let me transfer purchases to iTunes. What do I do to make a backup of my apps, update, and jailbreak? Thanks in advance.
I tried using the "transfer purchases" to make backups, but it's not working.
