i have looked myself out of my mobile

the only way to do it is put the password in too many times till it blockes then call at and t or whatever you are with and they will give you a puk code then you will enter that and after it asks for your new code it is the only way buddy and a good idea would be to right the puk code on the battery or something for future refrence if your too scared to block it then call for your puk code first just say you have put your code in too many times and it has blocked
