Hey guys, I was wondering if I should jailbreak my iPhone 4 or not...I've had it since launch day and I like it a lot. I've already jailbroken my ipod touch like a year ago, so I'm not new to this. I'm just really confused because ive never done it to an iphone. Can I "un jailbreak" my iphone if I dont like the way it is? and how often does the iphone "brick"? Should I jailbreak? Thanks a bunch.
