How do you unblock blackberry?

Answer 1

First off, your blackberry would have to be a Quad Band phone. Secondly, you could either take your blackberry to a phone store and have them enter a code on which it could unlock your blackberry phone for a fee of about $50 depending on the store. Or you could look online for a phone code and do it yourself, but doing it yourself is something i would not prefer doing because you could risk locking your blackberry phone completely.

Answer 2

Try taking the battery out and putting it back in. That should unfreeze it
