I have PkgBackup from Cydia installed on my iPhone4, and i was wondering if it will work as i hope it will. For this new jailbreak, after i back-up my phone in iTunes, i download new ios with iTunes, then jailbreak. After that i open Cydia, and add PkgBackup, then i hit "restore" in PkgBackup(while phone is still plugged into Mac) and hopefully everything that i had in Cydia will reappear in my phone. If i'm wrong, than i need some step by step help. Just to play it safe, i've written down everything that i have in Cydia. By the way, does anybody know anything about "tinyumbrella"? My neighbor said that his son used it on his iPhone, but the kid lives in SoCal, and i'm here in Fla. Thanks in advance for any help.
