i used to have at&t before it was bought out by cingular and now i have verizon wireless.

living in brooklyn i got decent service with the att/cingular but much better results with verizons service over all.
my only complaint is the motorola phone i used with att was much better sound wise then the current verizon cell i have now, especially with the placement of the ear-hole section of the phone itself.

im also buying a sidewinder for myself and a few friends as gifts because they seem to produce good reliable results.
