Whoever said your plan had to say "Sero" cause mine only said F&F 500 and I am now on Sero Premium with a Samsung Epic 4G. The only thing that hurt was the cost of changing phones. The Epic with a price tag of $390.41 - $100.00 MIR = $290.41 still on the high side. Glad I got $150.00 for my Touch Pro 2, so after doing the math, I got my Samsung Epic for around $140.00, but still have to wait for the damn rebate though.
Just don't ask me how much I paid for my Touch Pro 2 back in September of last year
