Hello, I have had an iPhone for about a year now. Recently, I have been wanting to Jailbreak my phone. Currently I am on the 3.1 (7C144) firmware. My question(s) are: if I do jailbreak my phone, what is the most simple program to use? also, if I do not like how the jailbreak is, can I just restore it? and if I do restore it, will that bring the phone to the original firmware it came with, or the most recent that is released (such as 3.1.2) ? Thanks for any responses!
