Problem 1: Putting it on was the first thing I did with the phone. Three weeks down the line, I took the case off in order to clean the screen protector thoroughly. To my horror, I have numerous scratches and markings on the chrome and black plastic which were *not* present on the brand new iPhone 3G when I put the case on. The case has in fact done more damage to my phone's casing than what would have occurred if I used the phone without a case for three weeks! I can confirm that no dust or particles were visible on the phone before applying the case (which may in turn have been abrased by the case). Problem 2: The 'rubbery' coating on the plastic is already starting to wear off, and in no minor way either. It has left several areas of completely clear plastic, and the case (and phone) look tired and worn even though both are less than a month old and have been subject only to light use. I am really annoyed with the poor quality of this product - has anyone else experienced the same?
