The HTC HD2, the Swiss Army Knife of smartphones, now has a Jelly Bean port to play with. There's a list of things like the camera and video playback not working, so it's no daily driver just yet but the core functions -- data, Wifi, Bluetooth, and calls do work. Given the huge global developer support the HD2 has, we wouldn't be surprised if everything gets working in short order. Who needs Tango when you can have Jelly Bean?
