iPhone 4 Fix for Reception Problem

I don't know where this fix idea originated, but when I heard about it I was stoked.  I wanted an official Apple band in yellow, and now I can see what it looks like.  Plus I follow Livestrong and Lance Armstrong.  I like winners,  Apple, USA, Armstrong, profitable corporations.  Very difficult to be a strong happy individual.  But I digress.  The solution to a problem I don't have is cool.  Look at it, love it.

UPDATE:  I shoulda known, the tip comes from Lifehacker
