Hi, I'm not sure if anyone has had this issue yet. I was in the security tab of settings and was checking out the SIM Card Lock. Of course, I ended up locking myself out of my phone. Now it is prompting me for an 8-digit PUK code. I tried calling customer support and my local store and no one seems to know how to fix it. They said that this is not a world phone and does not have a SIM so it should not be asking me for it, but it is. I'm wondering if this is an HTC issue. Anyway, any idea on what I can do to fix this? I am not ready to send this back to HTC or anything for a fix. Any thoughts are appreciated.
