I agree, depends on your locale....
I went through Bellsouth Mobility (now called Cingular), Sprint PCS, US Cellular, Primeco (now called Verizon), AT&T, and finally settled on Voicestream (was Powertel when i first switched to em).. 🙂 whew...
The ONLY one where i got coverage in my house was Voicestream, all the others sucked here in Florida... at least for me...
