Before you even think about QuickPwning, if you have a bunch of apps installed (I had 4 pages worth) DO NOT QUICKPWN! Doing this will MOST LIKELY cause your iPhone to get stuck on the Apple logo upon reboot after QuickPwning, and doing this twice through Vista and XP confirms this. If you're like me and have LEGIT, NON-Jailbroken 2.1 firmware already running, these are the steps you should take to do a proper QuickPwn:
1. Sync/Backup your iPhone completely. This is important should anything go wrong.
2. Backup that backup. Yes, you read right, navigate to your MobileSync folder and drag the "Backup" folder to a usb flash drive, or external hard drive, or make a copy to the desktop. This is because once we jailbreak and do a backup with jailbroken firmware, it will overwrite your previously clean, 2.1 backup, and we don't want this.
Location of Backup folders in Windows: (credit to SwedishHammer, Mortagon and AFMagnum for additional info):
Vista - C:\Users\(YOUR USER NAME HERE)\AppData\Roaming\Apple Computer\MobileSync\Backup
XP - C:\Documents and Settings\USERNAME\Application Data\Apple Computer\MobileSync\Backup
Make sure you have folder options set to allow showing of hidden files and folders or you might not find the Backup folder!
So I have 8 themes from cydia/installer, a couple keyboard apps from cydia, and the att logo from cydia. I have 4 apps from the AppStore and 10games from the AppStore. If i skip steps 1 and 2 and 8-10, i will ONLY lose the 8 themes, couple keyboards, and the att logo right? will i lose cydia andinstaller? Will I lose contacts?
All the AppStore stuff remains in my itunes and will come back once i do a sync after 2.1 jailbreak is installed?
4. Make sure you have STOCK, LEGIT Apple 2.1 firmware/ipsw already on your computer (you should have this if you're running 2.1 already). If not, go get it. Google is your friend, so is MacRumors.
So when I open iTunes...it says that there is an available update for my Iphone - version 2.1. will that not work in terms of bringing me to backto stock?
Does this mean I should download 2.1 fw from apples site manually versus automatically having it downloaded to my phone like iTunes instructs?
Sorry for the dumb questions as i am pretty technically challenged...when i jailbroke my 2.0.2 using winpwn...i had no idea that i had to - SHIFT+click'RESTORE' - in iTunes to bring up the pop-up that lets you find the jailbroken fw/ispw...i'm a PC user so i just clicked restore thinking a windowwould pop-up to let me browse and find the new fw/ispw...but nothing my phone just went into the normal restore process of annon-jailbroken iphone and wasconfused as to how to restore with the jailbroken version of the fw/ispw....
Thanks for all the help...
