We saw the Web portal to Windows Marketplace for Mobile go live earlier this week, and now the one-device app has gotten a refresh as well.

So what's new in Version 1.1.1109.0000? Visually, nothing. Everything looks the same. Perhaps just bug fixes? (We were having problems with the Marketplace apparently hanging as it was installing the occasional app. The app itself would load just fine, but the Marketplace app balked.) Perhaps more behind-the-scenes support for things to come? Security fixes? (Update: Just read over the advanced security white paper again, and it does tie in with the Marketplace app, so that's a pretty good bet.)

Let the speculation begin! And sound off in the comments if you've found anything new.
