Im stuck at this stage as well, I dont mind paying to unlock my phone, i've already paid £3.99 to get what i thought would be a code i type in the phone to unlock it, but all i got was a load of instructions using XS++, but as I get the same CID53 I wont be able to use it. Im not going to risk follwing that video as it looks very difficult and i dont want to waste a stack of time and possibly breaking my phone. Is there any other way to unlock my K770i from voda to O2 like buying a code that i type into the phone ???? Any help is much appreciated.
