2 years ago: Casio "GzOne" Type-S on Verizon
Today: HTC Thunderbolt on Verizon
Used T-Mobile briefly in between, with the G2 by HTC.
T-Mobile got me hooked on smart phones, wireless data, and the portable wifi hotspot, but failed to impress with their network coverage, especially in the far-out burbs and rural areas. I knew from the second month that I would switch back to Verizon sooner or later, and so I did about a week before Verizon ended new sign-ups for unlimited data.
