IPhone 4 (Verizon) monthly cost?

I have an Env touch right now and i think i pay 30 dollars every month. If i got an iPhone 4, with the smallest data plan, smallest calling minutes, and unlimited text how much would that be monthly?

$60-$70 depending on Taxes.

Minutes $30
Smallest Data plan $15-$20 Depending on where you live
Unlimited texting $10
Plus Tax $5+

So $65 bucks just for one phone.

I don't know
