Verizon's CFO Fran Shammo mentioned at the J.P. Morgan Technology, Media, and Telecom conference recently that anyone migrating from 3G to 4G devices won't be able to grandfather in their old unlimited plan and will have to instead take a data share plan scheduled to launch this summer. That way, not only are you burning through data faster, but you're also splitting it among friends or co-workers. Everybody wants that, right?
Those of you that scrambled to get unlimited data plans on Verizon before they dropped the axe on it will have to carefully consider your next upgrade.
To be fair, this will make it easier to split data between devices, which is a common eventuality for those of us using both an iPad and an iPhone. Still, this sentiment is in direct opposition to Sprint, who has pledged that they'll keep unlimited around even if an LTE iPhone is eventually released. The question is, how long are you going to be willing to hold onto your iPhone 4S with an unlimited plan before being tugged into a limited (but faster) world of LTE? Will Verizon still rip you from the warm embrace of unlimited data even if you stick with a 3G device?
UPDATE: Verizon recently clarified that no, they won't be forcing people to switch to the shared plan, though new subscribers still won't be able to pick an unlimited plan.
