the difference between redsn0w & PwnageTool is the platform it can be run on. (redsn0w = Windows, PwnageTool = Mac). plus, PwnageTool additional feature of being able to create custom firmwares (ie. new firmware with old baseband).

the question of local/foreign iPhones does not matter. and unlock relies on ultrasn0w, which is an unlock, not a jailbreaking tool.

kudos to b00n for allowing JB discussions to be back. miss the old days on discussion of unlocks & Wintherboard themes.

well, one of the best ways to backup your contact is to sync with Windows Contact/Address Book. there's an option in iTunes.

apart from that, before any update of firmware, you can opt for the SSH method of accessing SMS, Contacts in your iOS file system and copy them out (backup) and place them back once update if complete.

if u don't have another backup of your current backup, i am afraid you will not able to retrieve them.

p/s: i never restore from backup as during the old days of 2.0 and 3.0, restoring from backup do mess up your phone in some ways.

so what's the point of your post then if you're not willing to share?


well, like what i have stated in my previous post, if you're on a jailbroken phone, restoring from previous backup do mess up with your phone in some ways eg. battery drain & ocassional hang issues. hence, only manual backup would b able to avoid these.
