yannyb, I've been giving some updates on the 2.0 FW status on the following thread in the XBMC forum
http://xbmc.org/forum/showthread.php?t=31157
The short news is that since I don't have a mac (Linux/Windows user here), I can't get access to the 2.0 SDK so I can't even build the app for this firmware.
You can do one for jailbroken phones. You don't need the SDK for that I don't think.
