Enjoy! Rate 5 stars and post if you have any questions.

would tthis work if already 3.1?

I dont think it would work. Works if your 3.0 already jailbroken. You must downgrade to 3.0 & jailbreak it then use pwnagetools

No, I say in the video that it has to be on 3.0 with jailbreak before you can do this, sorry. Maybe downgrade? I've heard you can't, but you may want to try it just in case. You must login or register to view this content.

Yes, I had 3.0 update and then jailbreaked it
