I was wondering the same thing, you will also notice that the About is not visible. Either hidden as they scrolled down on the menu, or just not there. I really can't answer more information than the photo provides. Sorry.
All I could squeeze was that it was from .2675 (Newest OS is 2670), and even that is just a rumour. I am not even sure we will see that build, maybe something has to be tweeked.
Nice Oniberry! I know how those screenshots go, sometimes you just find them on a flash drive or something. But good work on securing it!
Hopefully they release on the 28th, would make a good birthday gift to me. Not sure I'm on their friends list though after my marketplace work. Perhaps they'll try to get this shipped before the end of July? Would give them a little more credit and allow them to divert the bad press of no native PIM while they focus on the launch of the new OS7 phones in August.
