anyone know how to crack a security code on a phone??? i've got a verizon lg vx8300...

the problem is one... either i set my security code and have no idea what it is... or someone else did for me without me knowing....

two... the lady at verizon said asked it if was my "lock code" or "security code"... thinking it was my security code...
i locked my phone thinking i knew that code...

well apparently it's the same thing and now i can't use my phone at all!!!!!!!!!!!!!!! i don't want to run to the store to fix it either!!!

reps to whoever helps.... (i've tried every code i've ever used for anything... and tried taking the battery out to unlock it... nothing works.)
