Terrible case for those that want to put on "IFROGZ" screenprotector or anyone else's for that matter. They ruin anything resembling a screenprotector. Returned two of their cases and received a credit on their site for $20, but they're yet to put any iPhone 4 items back on their website...
As of September 14, 2010 they've updated their site, but still uncertain about adjustments to allow their own screenprotectors to fit while using their own cases. No explanation as to FIXING the previous problems. I'm still warry of purchasing anything from iFrogz, until they post an explanantion about the problem with previous iPhone 4 cases and their screenprotectors...
