How to jailbreak my iphone 4 without a computer? - 1
You take it to a store and have them do it for you
You need to use software on a computer.
Email me at mail2paul13(a)yahoo.com and I'll walk you through the steps.My iPhone is jailbroken so I know how to do it all. (You need a computer to do it. It's not possible without) before you email me please check what iOS your iPhone is running. If its 6.1.3 then it can't be jailbroken. I'm sorry.
