O2 do this already. Threaten to leave 'cos u want a crackberry from Orange and they might (depending if they have any) offer you a resurrected jeebus phone for £35 a month. Then all you have to do is notice *ahem* a part is missing, lets say part of the charger and they'll send a courier to pick up the old one and give you a brand spanking new one... Good service as always from 02.
