I'm going with universal release dates, since really this is just another iPhone 4 just a CDMA one, if there was some other tweaks to the internals, i might agree with dual release dates, but they're not, they already said they'd been working for a while on doing a CDMA one, so whats to say that they haven't made the next iPhone with CDMA version in parallel to? so i think there will be a verizon phone released in June with the usual rest of the world one. especially since its probably only going to be a slight tweak like the 3G - 3GS.
