No problems at all with cellunlocker. I ordered a unlock code for my Samsung Galaxy Note, which they delivered pretty quick, and it worked fine. There was one minor issue, which to be fair is not their fault (I'll write a note to them about that).
Four stars below for price because I found one place, which I have used before (equally good) for less price. Overall, recommended, with no reservations.
