Well,who is your cellphone carrier/provider?

My mum got me a celly for my birthday yesterday and I got Cingular.It's actually a bit of a dissapointment 'cause ALL of my friends and almost everyone in my family(besides my older sister),uses Verizon.Even my mom who got me the Cingular phone...

Anyway,who is your cellphone provider?

NOTE:Am I using the correct term,provider?
