Think about it. Right now if you want to go month to month you have to pay full price for a phone (about $600). With the new plan, you are month to month, but buy the phone over 24 months instead of paying up front. Do you really think that Verizon is going to allow you to pay about $300 less (half of $600 phone) than what you pay now if you want no contract? How likely is it that Verizon is going to be so generous that they are willing to lose $300 per year for each person who wants to sign up for this plan? I guess we'll have to wait and see, but doesn't AT&T require you to return the phone?
Yes, and so does T-Mobile. The only way they would let you keep the phone is if you keep paying them for it. But #1, that's just additional "credit" risk for them (i.e. tacking on multiple $30/month "plans" and an unlimited ceiling for ETFs), and #2, that doesn't even workout as well for them because they're going to refurb it and sell it for more than 50% when you turn it in.
Though you're right Miller, I also can't find anything official from Verizon stating the device has to be turned in, though I'm confident that's the case.
