I want to sell my iPhone because the home button doesnt work...I have some buyers but they are only interested because my phone is jailbroken/unlocked. however I cannot restore my iphone to a fresh jailbroken state because my home button does not work and I will not be able to enter DFU mode. I have sensitive info on my iphone such as contacts, settings, emails, etc. can i rejailbreak without homebutton?

download iliberty+ and use other options and you can press a button to go to DFU or restore mode to do your thing and kick your self out of it as well.. thats what i use sometimes, just do not jailbreak or unlock or activate which are the main options on the program.

does iliberty+ work with 3.0OS? I use mac, but I have a windows PC I can use.

Do I just use iliberty+ to send into DFU mode and then Pwnagetool will automatically detect it in DFU mode?

I just want to be sure, I dont want to pester you. Thanks for your response

iLiberty+ is for 1.x firmware.
