Now I've thought about this and to be honest there's no real reasons why this shouldn't work, so;
Buy the iPhone, take it home and activate it with any of the tariffs.
Phone o2 on the Saturday and cancel the contract under the 14 day peace of mind guarantee, they'll no doubt tell you take the iPhone back to the store for a refund so just ignore that.
Buy a Nokia N95 online with the Online 35 tariff which gives you 800 minutes and Unlimited texts, add a web bolt on for £7.50 which brings you to £42.50 a month.
Sell the N95 on e-bay which should net you around the £295 mark, stick the 35 online tariff sim into your iPhone and you're home free, of course you won't get Wi-Fi access or Visual Voicemail, but might be worth it.
