Saw the above phone in Asda (swindon) a few days ago. Was £8, which is more than some of the other deals on here for this phone, I know. But, for this one you didn't have to buy an airtime voucher.
So £8 was all you pay and you also got a T-Mobile SIM card. I assume it is locked to T-Mobile, but I can't confirm this.
Can't see it online so must be instore only. Hope some of you manage to get this.
