Live in an unfortunately located apartment or rural area (or any other reception phantom zone)? Verizon will let you turn your net connection into 12m of 3G. This is still, however, a pricey fix for bad service.
The 3G Network Extender - a generic black box from Samsung - will allow use from up to six phones at once, and no additional fees will be tacked onto your plan. [Verizon]
