I just got a new white iphone 4. I shared with the verizon sales person that I didn't think the proximity sensor would work with the screen protector. He assured me it would. I got home and it would not. It works great with no screen protector, but not with it on. I bought an otterbox defender online and I cut out the clear protector over the proximity sensor. Now, it will work when I am in a very well lit room or outside, but not otherwise. Also, the auto-brightening has the same issues - work in well lit area, not in others. I called Apple and they said that the 3rd party sellers will be making new cases and screen protectors for the new white iphone?? Anyway, I like the phone. Any suggestions for how to get the proximity sensor to work when not in a brightly lit area?
