How to jail break or unlock a iPhone?

Is there an app or does this have to be done by computer

You can unlock it online.

Yes, there are many youtube videos and websites telling you how to jailbreak, however be VERY careful. It is not hard to turn your iPhone into a useless blob if you don't do it correctly (I speak from experience). If you want it unlocked, I highly recommend getting a factory unlock like at iPhoneUnlockedCheap.com They do it remotely, so they don't touch or modify your iPhone and it is permanent unlike a jailbreak unlock.
