Hello
Finding a PUK (Personal Unblocking Key) number is not tough job. To find a PUK code all you have to do is call up on the customer care number and ask them to help you with the issue. Before they provide you the PUK code, they will ask you several questions. You need to give them the appropriate information. Customer care of your service provider are the only source from which can give you the PUK code.
At the time when you enter a wrong pin number three times. The phone asks you for a PUK number. The PUK code is generally eight digit number This PUK number is an unlocking code which helps you to unlock the phone and use it. If you enter a wrong PUK number 10 times than you simcard gets rejected. Then you will have to but a new simcard. It might happen that your phone might ask you for PUK2 after you enter your PUK number.
Hope it helps, if so do rate the solution

I have the same problem. Trouble pairing but finally I got the SYNC to find my U430 and paired but the SYNC never connects with the phone.

It sounds like he removed the at&t software, and "flashed" it with generic software. Should work fine for making and receiving calls, but without the at&t settings in your phone, internet and texting probably won't work.
In my opinion, it would have been better if the shop had explained what they planned to do before they did it so you would have a better understanding of what was going on. Hope this helps you.
