Um, if you enter it wrong enough times, i think it will ask you for the PUK code. To find out this code, you will have to be an authorized user for your cell phone account. Call your provider and tell them you need the PUK code. They will give it to you and after you enter that in, it SHOULD reset everything. Whatever you do, DO NOT ENTER IN THE PUK CODE WRONG!!!! If you do it more than 3 times it will kill your sim.
