It looks like Apple made some tweaks to the iOS 4.2.5 we saw at the Verizon iPhone’s launch event, and is now upgrading it to iOS 4.2.6. The firmware is available for you to download and mess around with, if you’re into that sort of thing that is.

The firmware weighs in a 652mb which is 28mb more than the iPhone 4 GSM’s latest release.  We are assuming that 4.3 is going to be ready pretty quickly after launch, with its hotspot features being one of the prime Verizon advantages over AT&T’s service.

Verizon iPhone are now probably in the wild with last minute testing going on and store users and insiders using them.  Mossberg probably has one and Woz two.  And maybe even some of the guys at Best Buy?  Nah.
