World of Warcraft Mobile Armory for iPhone was updated earlier today to version 3.1.0. The update adds improved mobile auction house functionality, visual tooltips in chat, additional guild features, and other general quality-of-life improvements to bring the mobile app up to par with Battle.net's latest web interface and expected on-the-go functionality.
The mobile app, the Battle.net web interface, and World of Warcraft's built-in UI all seem to be continuously competing with each other to push the capabilities of WoW's virtual marketplace while simultaneously struggling to keep up with each other. It should be interesting to see how the other two platforms follow up on this app update.
