Microsoft is set to launch Internet Explorer 9 tonight with a big bash at SxSW.  According to a Tweet by Joe Marini, Windows Phone Web Platform Program Manager, you can at least get a glimpse of the mobile version as well.  He will be packing a WP7 phone sporting the new browser and invites attendees to check it out.

Though it is widely thought that the new browser will be rolled out as part of the highly-anticipated Mango update, we could see it much sooner.  For more detailed info on what to expect from IE9from Marini himself, check out our previous coverage.
