Antenn-aids are described by the seller as "custom vinyl sitcker[s] for your iPhone 4." The Band-Aid for your iDevice is designed to be placed over the lower left corner of the antenna. And while the seller takes great pains to ensure that buyers understand that the Antenna-aid is for entertainment purposes only, chances are, the solution will work at least as well as tape or another type of protective covering.
The bandages are being sold in packs of six for $4.99. Each Antenna-aid is a different color so you can color-coordinate.
How useful (or not) the decals actually are is kind of irrelevant. We're just really taken by the ingenuity and creativity of such a creation. As much as I love my iPhone 4, I still find the idea of having to have a bandage for the device just to make a phone call (assuming you hold your phone while touching the problem areas) absolutely hysterical.
