Here I'll set this straight:
1) ANY Verizon-branded SMARTPHONE/PDA Phone not manufactured from Blackberry can be used on the Verizon Network without a data plan.
2) If you purchase a verizon-branded blackberry, you HAVE to get a data plan.
So the XV6700, the XV6800/Mogul, the SMT5800, etc does NOT require that you have a data plan.
Cheers,
Jim
