I demo'd Mobiola webcam and while it did work, it also caused a complete wipe of my phone. It crashed and when it came back up, it was as if I had done a wipe. Absolute stock settings and no data.
That was maybe a year ago so perhaps an earlier version than now. But if you demo, do a backup. Overall the BB does not make a good webcam. It is hard to get it into a good cam position such as on top of a monitor.
