Wilson Electronics has help for iPhone or BlackBerry users who live or travel in places where cellular signals cut in and out or can't be received at all. The Wilson iBooster is a plug and play cellular signal amplifier and battery charger for 2G and 3G phones with models for both the iPhone and the BlackBerry Curve.
The video above is a realistic albeit homespun evaluation of the iBooster that is representative of the positive user reviews this signal enhancing device is enjoying on the Internet. Wilson's website also links to a slicker YouTube video.
The Wilson iBooster lists for @279.95, but sells on Amazon for under $200.
