Best Buy is giving out and/or installing Zagg's invisibleSHIELD 4FIX for people complaining about iPhone 4 reception problems, anecdotes suggest. While most invisibleSHIELDs are meant to cover the front or back of a handheld, the $10 4FIX package consists of transparent strips covering the iPhone 4's antenna band. These should in theory prevent a wraparound hand grip from cutting off signal.
