When a developer here on XDA is credited as having helped with not just one, but two Jelly Bean ports for the hottest devices on the market, people start to notice. XDA Senior Member randomblame has not only succeeded in doing that, but also in making his own port for the Acer Iconia A500, leading it to claiming the title of first non-Nexus tablet to have Jelly Bean.

Already on it's second version (damn he's fast), the only things not currently working are:

No audio

No wifi

SD card

USB not mounting flash drives

The developer has even written up a basic guide to help other members with porting Jelly Bean to their own devices, and has made himself available for assistance through IRC channels (please don't harass developers through PMs).

If you're a developer looking to help out or a user just wanting to support an awesome dev, head on over to the original thread and show your A500 some tasty love.
