just googled bout it. haha. only for hd7 i guess cuz my mozart dont receive any update lately

thats one naughty banana

my mango just got updated to version 7712

Here're top 5 improvements in build 7712:

Application platform APIs are now locked; you can feel confident to start getting ready for submitting your apps next month.
Emulator now has a nifty screenshot capability built in, allowing you quickly snap quality images of your app without the need of separate tools or cropping time. The images are great for use in app submission process or to share on your blog or with folks such as my team (hint hint).
The profiler has been greatly improved and provides memory profiling.
As of this drop, you can install NuGet into the free version of the WPSDK tools.
The drop includes an initial peek at the Marketplace Test Kit; with the RC release, you'll be able to use the included version of this toolkit to test your XAP file against the same certification testing tools that we use when ingesting apps for the Marketplace. For this refresh, it's there but not fully functional.
