Ok so Cellunlocker refunded me as they can't unlock it yet. Tried various places and no luck.
Knew might be the case and as on rolling 30day contract (whole point of having a contract free phone) I've simply moved to T-mobile for now in an equivalent tariff to the 3 one. Can always switch back if I need to in 3 months but all my goodwill for 3 was lost in the 30 mins and two separate calls with "James" in their call centre......Much better signal now too as I'm only 5 mins walk from T-Mobile head office so all is well that ends well. Sorry for those of you still on long term contracts though, hopefully someone will get the unlock codes soon.
