Hi! Installed yesterday night and got up & running only this morning after several problems with restoring my backups and/or deleting data…some of them my faults to be honest 
I confirm I have no problems with the following services/devices:
- dual SIM support (I tried both SIMs and they are able to call and receive voice and SMSes);
- 3G data + USB tethering (my first SIM is 3G activated and I’m writing this post using my pc with tethered connection
) - GPS (great! my first fix after 16 seconds!)
I didn’t try yet WIFI and Bluetooth because had no time to test them, I’ll report something tonight or tomorrow morning.
Again thank you very much @chrmhoffmann for your great work
