When we launched Flash Builder and Flex 4.5 in May we said that we will have an update a month later that brings Flex mobile development to all three platforms: Android, iOS, and PlayBook (BlackBerry Tablet OS). And this is the update we were talking about.
So starting today, you can build all sorts of amazing mobile apps that run across these different devices.
If you want to find more about this, make sure you register for Adobe Developer Week. This is a series of webinars that will start today.
