AT&T and T-Mobile may have gotten there first but Sprint has one-upped them all.

What's the prize?

A $99 cell phone plan that not only includes unlimited voice but also texting, GPS, and Internet data.

That's a great deal and could be the price point that gets small business users to dump land-line phones altogether and move to a smartphone as their sole telephone device.

I know I'm thinking about it.

I'm off-contract on T-Mobile right now -- time to do some shopping!
