According to Engadget, Apple is serving up (yet another?) new beta firmware, this one doing away with the (confusing?) 1.2.0 designation and lining up squarely behind Steve Jobs' announced 2.0 labeling.

Aside from some VPN, mail, and ActiveSync tweaks and re-org's, Engadget can't find much else aside from the shiny new version release, but as June gets closer, no doubt Apple's engineers will get busier!
