I'm trying to convince a friend to switch over from 3 once her contract expires in about a month time. However, her HTC desire is locked to the 3 network. After googling around, I have found ways to unlock it without paying the £20 or so to ask 3 to unlock it.
I just want to know if anyone has done this before? And did they experience any problem with the unlocking and if the unlock phone works fine with giffgaff? Thank you.
