Apple has just released iTunes 10.1.2, a minor point update that claims to provide "a number of important stability and performance improvements." Unless they're planning to update it again in the next few weeks, might it not also include support for the Verizon iPhone and iOS 4.3?
Once you've installed it let us know if you see anything else new!
UPDATE: Sure enough, eagle eyed readers point out CDMA iPhone 4 compatibility is mentioned in the release notes. Why not jsay Verizon iPhone 4...?
