iPhone Problem

[Bennie-Mac]

HI guys, i recently sold an iphone 2g on ebay, now the buyer has come back to me and said it wont work with his o2 sim card. According to him when the sim is in it says "slide for emergency calls" and there is a symbol telling him to put it on charge, if he presses the screen it comes up with the iemi number. Does it just need reset or is there something wrong? Its an o2 sim and the phone is locked to o2 if that helps.

Thanks

Does it need activating through iTunes again?

He can always try a restore, doesn't take long and he wont be losing anything.

Thats what i thought, he seems a bit thick so im hoping theres not too much hassle..
