Wilson (the folks who make the "trucker" antennas, not the sporting goods company) just introduced a gadget that boosts cell phone signals by about 20 dB. That could make a big difference when you're in a fringe area. It's called the Sleek Universal Cell Phone Signal Booster and costs $129.
The Sleek looks like an oversize phone car cradle. The kit includes a suction cup mount for the windshield, and a mount with an adhesive back for more permanent attachment to the dashboard. You attach the Sleek to the cable from an antenna. It works best if the antenna is external to the vehicle, but even in the car the antenna will help.
The Sleek requires power to work. Included in the kit is a 12V to 5V DC (USB) converter that fits in the power port of your car. A second USB port on the Sleek lets you charge your phone while using the Sleek. There's an optional power supply for use with 120V AC if you want to boost the signal inside your home or hotel room.
The Sleek works in two frequency bands that cover phones from the major carriers. (That's 825-895 MHz and 1850-1990 MHz.) One exception is the frequency T-Mobile uses for Nexus One data service. But most cell phone voice and data service signal strength is boosted by the device.
