wish i would've seen this thread before i did what i just did, or asked some questions like ts did at least. Anyway, here's my situation:
I also want to sell my ipad 2. My ipad 2 was not jailbroken, so i went ahead and did the jb with absinthe, thinking it would completely wipe my ipad and it would be factory fresh with the jb in place upon completion. When it rebooted, i noticed the jb took effect but all my old settings, etc., were still there. So i then proceeded to erase all content and settings. My ipad rebooted to factory settings, but with the cydia icon still there. Except, when i click on the cydia app, it opens for a split second and closes. I also can't jb it again because absinthe says it already is jailbroken.
Help. What do i do? I want to restore this to factory 5.0.1 settings, with a jailbreak, for sale. Can i get there from where i am currently? Got ahead of myself, screwed up...
