Simply place this miniature miracle over the lower left corner of your iPhone's sensitive antenna area to improve signal performance. The added girth of Apple's free Bumper case is unnecessary when you can apply Antenn-Aid.
Expect to pay $4.99 for the biggest little signal-loss healer on planet earth. You'll get a set of six designer colors including natural skin tone 'peach'.
It's not just a temporary band-aid for a massive design flaw. It's pure genius!
