i have a 20gb ps3 and bought a 250 gb hdd to swap and i stripped the blue screw. is there anyway i can get the blue screw out without calling sony?

They have a "tapper" you can buy from most hardware stores....what it does is uses reverse threads to tap into the screw and allows you to remove it.....If you want an easy fix you could get a slightly oversized flat head screwdriver and tap/force it into the head of the screw with a small hammer after it's in you know what to do.
