Cell phone antennas and amplifiers are frequency specific (more info).

The Wilson iBooster Amplifier has been discontinued. In its place we recommend the Wilson Sleek Universal Signal Booster. The Sleek is an all in one cradle combo that boosts signal to your cellphone.

Wilson Electronics iBooster Amplifier for iPhone 2G, 3G, 3GS, and iPhone 4 is a lightweight, versatile product that enables you to place your iphone in a convenient location in your vehicle and use it with a hands-free device such as an ear bud or Bluetooth product in addition to enhancing the signal strength via the built in Wilson Signal boost amplifier and keeping your iphone charged up via the built in charging port. Doing so lets you keep both hands on the wheel, thereby maintaining your safety while allowing you to carry on a cell phone conversation. Wilson Electronics iBooster Amplifier for iPhone has the added benefit of a built-in cell phone signal amplifier/booster designed to improve your cellular signal up to 10 times and help you stay connected in places you never could before!

Here's how the Wilson iBooster system works: A Wilson mini-magnetic mount antenna (included) mounted on the outside of your vehicle communicates with the cell site, and the built-in iBooster cradle amplifier booster communicates with your cell phone. The outside antenna collects weak cellular signals and sends them to the amplifier. The amplifier boosts those signals and transmits them through the cradle amplifier/booster, significantly improving the performance of your iPhone. 

Note: In order to maintain improved signal, your phone must be left in iBooster cradle during usage (i.e. you must use a headset or hands free car kit.)
