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 use Antenn-Aid.
Expect to pay $4.99 for the biggest little signal-loss healer on planet earth. A set of six designer colors are provided for the fashion minded.
It's not just a temporary band-aid for a massive design flaw. It's pure genius!
