Here's a place for people to offer suggestions on cell phones.
"I used AT&T for my first year and was pretty happy with coverage. I switched to Verizon more recently, more for phone selection and in-network dialing than from any real problems with AT&T, and coverage has been good there as well." - Matthew Tong
"I used Sprint PCS in 2005-06 and the coverage was poor. Has anyone tried t-mobile? What other companies work well?" - Doug Turnbull
"I use verizon and the coverage is decent, but can be bad in hilly/mountain areas (e.g. university city around the 52, where I live). The minimum-price plan is also somewhat expensive." - Eric Weigle
