Hey guys, I have a tutorial that will help you get back to your old jailbreakable 1.1.4! (2.0 is jailbreakable, but the iPhone Dev Team has not yet released a new Pwnage Tool.) So let’s begin:
Step 1: Uninstall iTunes 7.7 and reboot
Step 3: Download Firmware 1.1.4
Step 4: Manually put your iPhone/iPod touch (firmware 2.0) into DFU Mode.
a) Press and hold sleep/wake button until slider appears
b) Slide the red slider to power off
c) Once off, press and hold the home button
d) While holding the home button, connect iPhone/iPod touch to computer by inserting the USB cable.
Step 5: Restore to firmware 1.1.4 in iTunes 7.5
Step 6: Jailbreak/Unlock
(I won’t list any links because you all should know what method you prefer)
