Just because I'm with a provider, doesn't mean I'm totally happy with it.
I've been with Verizon (formerly Airtouch, before that they were CellularONE) because that's who my parents have for their service. Their reception is not bad, but their equipment is really lacking. If it were my choice, I'd get a T68i from Amazon for -$30.01 after rebates and T-Mobile's $39.99/mo. plan. Then again, my parents pay my cell phone bill, so I'm not complaining.
