You can get a free Playstation 3 on £30 a month contracts, the phones are very low-spec though. Most come on £35/£40 a month contracts.
if you hold out for a little while, there may be some cashback/redemption deals in the future.
Towards the bottom of the iPhone contracts, there's a section that says "If you have a cashback or redemption offer..."
He wants a 'free' PS3 on an iphone contract. Not a 'free' PS3 on any old contract.
