On my device, I don't use mobile data 3G, but it turns on every time i connect the device to my laptop also every time I switch from "just recharge" to "usb storage".
They seem to be always switched off, if i set up the display luminosity they light up.
I think it doesn't work, I've tried it on a big qrcode on my screen, but I've seen were just some green random spots.
Panorama provides black screen and video recording crashes on stop.
Facebook contact pictures
The facebook contact pictures seem to be not merged with gmail contacts like in the stock rom, this is a detail not much important.
I really like it and I'll keep it during the week to test it, especially gps navigation, gps track recording, music, multitasking, and the way apps work on it. This is my first try of a custom rom on my Defy+, so if i missed some setting to solve those things above, please let me know. Hope have been useful.
