ClearBoost

While it definitely destroys the sleekness of the iPhone (if we wanted our cell phone to look like an old Treo, we would've bought an old Treo!), the ClearBoost for iPhone ($30) may be just thing for those in the boonies or for those times when one bar will make the difference between making a call and not making a call. In addition to ample protection, the ClearBoost case features a built-in booster antenna that will provide your iPhone with a better signal in certain situations.
