1. Please don't bump posts so fast. We're all volunteers here, and if someone sees your post and has an answer, you'll get one from the first post - even if it takes a few days.
2. Bring the tab into your carrier with a photo IS proving that iit's on an account you own/ (Or bring the account owner with you.) They can unlock it as soon as they verify (with the ID) that you didn't steal it.
