Can any kind person out there explain what a sim-free phone is? 
My current phone is on the point of collapse (mainly because I'm ready to stomp on it as it's so slow to do anything). I have a contract with Virgin which runs until July & I really just want to know whether, if I buy a sim-free phone, can I simply take the sim out of my old one and put it in the new one?
