Hello again everyone,
I did try to tamper with the phone occasionally to see if there was something i was missing or a new route to fix it.
Sadly none of it worked so i decided to ship the phone to HTC for repairs.
Wish me luck.
I'll keep you posted on what happens next. I have this dreadful idea that they'll ship it back and i try to unlock it and the whole thing happens again.
I'd like to thank everyone for their time and support, especially redpoint73 and timmaaa. Maybe sooner than later i'll be bugging you with more questions.
