Same here. I'm on AT&T, but bought an unlocked Verizon iPhone 6. I may not end up switching carriers in the next two years, but it's nice to have the extra flexibility for the same price I'd end up paying if I went with subsidized or Next plans.
Yeah, they sell off-contract Verizon phones at the fruit store. They're unlocked GSM global phones, pretty sweet. I got one because they were all my store had and immediately popped in my T-Mo SIM.
