If it's so damn urgent, why not search the forum?

When I forgot my lock code, I found everything I needed in this thread.

So long as you can get on Xterm or SSH to the phone and have some basic IT skills, you'll be fine. If you read the thread and need further help, I'll do my best to answer your questions if they're specific (i.e. "I get <error> when I do <action>").
