Posting because I don't know if anyone else has this same problem or not with cases. With my iPhone 3GS, I put an ifrog case on it and an encase. I also used a zagg shield. Worked great! After about 8 months of using that set up I noticed that dirt dust whatever gets in between the case and the phone and scratched he phone up pretty bad. My bezel is scratched, the plastic back is scratched. WTF..... Now I am reluctant to use a hard case on my new iphone or iPad. Anyone else experience this?
