I just bought Gadget Guard screen protector and now I am having a problem with my prox sensor on the iPhone 4 white. Never had that problem before. Before I take it off and chaulk up the waste of $$, does anyone else have this problem?

Yes I did too. I called Apple and was advised to take mine off and get an AT&T product.

What screen protectors does at&t make? They only resell accessories.

Call the manufacturer.
