Dan Frommer hits the nail on the head about the rumors surrounding Sprint getting a yet-to-be-announced iPhone 5 and then granting said mythical phone with unlimited data. Remember too that AT&T and Verizon both initially offered unlimited data.

I like this thought though:

I’m probably also in the minority here, but I’d be much more likely to consider switching to a provider that offered data-only iPhone plans, without a mandatory voice plan.

Count me in.
