PUK CODES :(

I was messing around with my phone today and somehow locked the SIM card which seriously pissed me off. Usually when I go into the PIN settings they let me cancel and it's all fine but this time it won't unlock and it wouldn't let me go back =.= GAWD there aren't any good phones anymore it's so annoyinggg :( Anyway I'm going to China AGAIN which means my Easter holiday has been thrown out the window == I was gonna go out with my friends to Stanley or something but NO we MUST GO TO CHINA TO GET A GPS. we already have like ten gps's why do we need anymore... anyway i'm seriously pissed and with the stupid science test coming up I swear i'm gonna explode TT^TT Anyway hope other people's lives are better than mine because if they weren't we'd be in deep shit.
