Must not be that urgent, as your question was answered 5 days ago.
You will need to explain what is not working in the directions I specified, as it does work. If you will say what didn't work, we might determine the issue.
I would recommend using www.horizonwirelessonline
for the unlock, they are also recommended in the link I posted above.
Proceed with the directions in that link. That link also elaborates with details step by step to guide you.
Please read. Good luck.
