[font=Arial]Can someone please help me, i've recently purchased a iPhone 3G off my mate as his contract ran out and he got a new phone. I'm just curious on how i would take it off Vodafone, i'm wanting to switch to o2.

I'm not looking to pay, so any of you little thieves can back off right now. There's a way, but i'm just don't fully understand how to. I've tried Jail breaking it, but there's still no success with it. Please Help i'll rep+
