My mate has asked me to try and get hold of an iphone 3gs for him. He needs it on the 3 network. I've tried his 3 sim card on a jailbroken 3gs,and it works, but it's a tethered jailbreak so when you turn the phone off you have to re-jailbkreak it using blackra1n for it to get pass the connect to itunes screen which is a bit of a pain.
Was just wondering if anyone knew whether a factory unlocked one or one unlocked by o2 themselves would work on 3?
Any help or advice is appreciated.
