I have a Zagg screen protector on my iPhone, and recently purchased the Speck PixelSkin case. The problem is the case raps around the iPhone and the front edges of the case tend to push up the edges off the screen protector. Do all theses type of cases do this or is there a specific case that only raps around the silver band and not the front screen? I'm looking for a simple all black case - or something to protect the edges. I have front and back screen protectors on the iPhone. How about the Apple Bumper - anyone use this with the Zagg screen protector? Does it push up the edges of the protector? Thanks.
