Thanks for the tip!If you got the Belkin screen protector for Apple to put on, make sure to read the reviews of the screen protector on the Apple site. Most of the people have said that the protector cracks very quickly, while others have stated that the screen protector cracked their iPhone screen. If this is true, it may due to the machine that they use to put the screen protector on, or employee error with the machine etc.
I must be one of the lucky ones. I've used Verizon's screen protectors (Not sure which one) and it cracked super easily). However, I've used Apple's Belkin screen protector and it's never cracked my phone and has protected it better than any other screen protector I've ever used.
