heyy... now you need to listen to me very carefully! Speaking to other members this way will not be allowed. Plus... before giving information to other members be sure you know what you're talking about. Thanks!
NEVER trust a website to Unlock your iDevice. Unlocking is easy to attain on your own w/o the need to pay anyone. Unless you need to buy a Sim Interposer... which is what you need to Unlock the 4S. The Gevey Ultra S will Unlock the 4S on Basebands 1.0.11, 1.0.13 & 1.0.14. We recommend purchasing Gevey products from Applenberry.com. They're a trusted supplier and offer warranties on all products they sell.
I have read that factory unlocking ip4s is possible by authorized service who can add IMEI to the Apple Whitelist. This is easily done by European service providers and your statements that it can't be done is not factual. Please do your homework and avoid posting wrong information.
My interest is in the true direction not nay Sayers.
