Apparently it works really well but you need to have tour phone rooted first
How do you commercial your phone to HDMI?
There is that stupid spell checker again.
Anyway the Galaxy SII has a mini USB jack that works as native USB so you can plug in like an external hard drive and it works fine ect but the main attraction is that there is a cable for that phone that is mini USB to HDMI since its also a HDMI enabled jack. There is a Motorola phone that has a mini HDMI jack already on it too.
