So I have a JB 4.2.1 iphone 4 and love it! I have all the coolest tweaks and apps, but I have sooooo many of them I just can't keep track! So if I wanted to update to 4.3 what program could I use to restore all of the perks and backgrounds/sounds after i update and re-JB? Or would I have to go thru and re-download and alter everything again? Even worth updating to 4.3? and also I used pkgbkup once and was unsuccsesful and now I have a stupid group in my address book that just freezes when I click on it....thanks for any help in advance~Chris
