Well the thing is that, i had someone buy an iPhone 4 from me while on his way back from Austria a year back from eBay and was using it happily with Gevey. But i accidently upgraded the base band while messing around with iTunes. Now that i've a locked iPhone i tried searching forums of A1, and I've come to know that they charge 150 £ for first year and 100 £ in second year and 50 £ after third year. And if you don't have the bill, they will charge you 150 £ straightaway. But the thing is that the unlocking site officialiphoneunlock.co.uk mentions in their website that they provide the unlocking service for iPhone 4 locked to A1 Austria for 19.99£ I just wanted to confirm the integrity of the site officialiphoneunlock.co.uk and if anyone has unlocked their iPhone locked to A1 Austria using the site? Thanks in advance.
