Well I must be honest, I am flattered to have the most viewed thread today, but disheartened at the lack of ideas.
Never mind! The guys who I went for the unlock (BBunlocking.net) said really sorry and gave me a full refund - which came through paypal immediately! So kind of them!
Took it to a cornershop to get it done instead. He has some snazzy device which does it instead of the unlock codes. Cost 15 quid though. Cant really complain given the HEAP of a phone I used to have!
Any ideas on the keys?
The unlock man said he could replace the top button (for the lock function) for 20 quid, and the whole keypad (so maybe *+green will work) for 45. I thought I could probs do it cheaper myself, as I cant imagine its rocket science. He said there was a risk of cracking the screen...is this true?
