I have a iphone 3GS and with a power support anti glare and a marware sportgrip. This combination works great as it doesn't peel my screen protector and cause it to bubble. I have this case since launch day and it's time for a new one. I wanted to get the incase slider but all the reviews say it will damage my phone. Right now I'm looking at the Griffin outfit which seems great or the Speck Candyshell. Will these cases cause my power support anti glare to bubble at the edges? I got a iskin solo and it made my screen protector peel in the corners Will the Griffin outfit or the candyshell work with my screen protector? if not, what case will?
