Wilson Electronics iBooster (iPhone)

Wilson Electronics has a good track record with cell phone signal boosters so it wasn't surprising when the company introduced a product designed solely for the Apple iPhone.

The Wilson Electronics iBooster offers a user-friendly design, and it fulfills its promise of strengthening your iPhone's reception. Yet, those pluses come at a price--both literally and figuratively. It requires a power source, so you can't wander far from an outlet, and the sky-high price of $279 will put it out of reach of many consumers. In a perfect world there would be no need for a signal booster in the first place, particularly one that costs almost as much as the iPhone itself, but any cell phone user can tell you that reception is never perfect.

The iBooster consists of three parts: a cradle for the iPhone, an external antenna, and the power cord for a cigarette lighter port. Setup is beyond easy provided you can arrange the various parts.

The cradle measures 4.6 inches by 2.6 inches by 1.75 inches. It's made of plastic, but it has a solid construction. You can attach it to your dashboard or air vent via the included clamps, which have adhesive backing. We love that the cradle accommodates both the iPhone classic and the iPhone 3G, even with standard cases. We were able to use our iPhone 3G with its case for a snug fit. If you don't have a case, the iBooster comes with an adapter to hold the phone securely.

The black antenna measures 4.25 inches and has a magnetic base for attaching to your car's roof. The connecting cord is 12 feet long, so you should have plenty of room for threading out your door or window, even if the arrangement can be a bit awkward.
