Re: I would like some flexibility... I agree with this!!! A la the VZNavigator, there is (was) an option where you can pay $2.99/day or $9.99/month. If there was some sort of a daily fee option, I would consider getting a smartphone. If any data is accessed, just bill the daily fee to the account (like the $1.99/MB charges on dumbphones)
Although the list of WiFi enabled devices are few (Ozone, Touch Pro2, Touch Diamond, Imagio), I think that the list is only going to grow.
