Roaming? (Or lack thereof?) Go with Verizon or Cingular.
Cingular is always the cheapest but with reception, it's hit or miss. In California's Orange County, Cingular's reception sucks, but in Texas, it's better than any other service.
Ask locals who live in the areas where you'll be using your phone how reliable their reception is.
By roaming, I meant the ability to take your phone out of town and have it work for you. Technically speaking, you are roaming whenever you leave the home coverage area, which is defined by a unique SID (System ID) number assigned to a specific carrier in a limited geographical area.
Verizon and Cingualr acheive their roaming coverage not only through their "native" coverage (company owned networks in different cities) but also through roaming agreements with third party carriers, where the third party agrees to carry a Verizon or Cingular customer's calls over their network when said customer is out of range from their carrier's own network. In Verizon and Cingular's case, such roaming is not only widely available, it's usually free for the customer, too.
With Nextel, you can roam to different cities where Nextel offers service, but Nextel uses their own unique form of digital technology, so it's Nextel or nothing--there are no alternative networks, so there's no roaming off the Nextel network.
With Sprint, you can also roam to different cities where Sprint offers service, generally at no extra charge. Sprint also has third-party roaming agreements in place; however, they charge the customer either by the minute, or by the month, to take advantage of these agreements, which is not ideal for the customer.
With T-Mobile, like the others, you can roam to different cities where T-Mobile offers service; however, if I'm reading their maps correctly, they don't allow the customer to take wide advantage of third-party roaming agreements, so basically, it's T-Mobile or nothing. (Someone please correct me if I'm wrong about this on plans they currently offer.)
Therefore, if you want the ability to use your phone at no extra charge in areas that the carrier doesn't offer their own service, the advantage lies with Cingular and Verizon. (And especially Verizon if you're serious about having coverage everywhere possible, because they offer digital/analog handsets that work in the few areas left where there is non-digital service available. Analog, AKA AMPS ("Advanced" Mobile Phone Service), was developed in the seventies, standardized in the early eighties, widely deployed through the eighties and nineties, and is still the one and only "universal" cellular language in the US.)
