So I still have my 2G that has been used and abused for 3 years and never had a problem. Still use it everyday to go the the gym with. I have this 4G for 2 weeks and have it wrapped in a rubber case and screen overlay. Didn't drop it, didn't do anything out of the ordinary. I take it out of the case everynight and clean it w/ a microfiber cloth. Took it out of the case tonight to see the whole back glass cracked! Please tell me this happens to more people so apple will admit that this "aircraft grade" glass isn't all that it's cracked up to be.
