A few readers (thanks!) sent us notes pointing out that Blizzard has updated the Mobile Armory app for the iPhone. The new version, 1.1.0, features a streamlined character selection screen, the ability to save and load custom talent builds (though unfortunately it doesn't look like there's any way to bring these into the game automatically -- you just have to choose points the same way), in-game reputations on character profiles, and a number of other bugfixes and user interface improvements.
The one big feature is that "Find an Upgrade" now works on the mobile app -- you can search directly in the app for a gear upgrade for any equipment slot on your character. That's a nice bonus; it means that while you're sitting on the bus with your iPhone, you can look through your gear, and figure out what you're going to be upgrading to in that waist slot the next time your guild heads up into Icecrown. I'd still like to see a little more integration with the game itself (a few MMO companies have hinted that they're pushing for more integrated iPhone tie-ins), but since the app is called Mobile Armory, and yes, is still free, I can't complain too much.
