How do I network unlock my Z10?
I recently had a GSM unlocked Z10 phone that I took over to ATT. I cracked the screen and had to send it in for repairs. The insurance company sent me a new phone but it is network locked to ATT. They will not unlock the phone because I switched services to a different carrier. They will not send me an unlock code at all. What do I do, can anyone help? I also took the phone to a cell phone store that kept it for 5 days and kept telling me that they were waiting on a code to come back before they could unlock it.
