Note to you and myself.
I only Flashed fiasco/rootfs so when i restarted all skype/gtalk/facebook accounts were intact BUT i didn't get skype video call and only way to make video call was to first call from my laptop (it has webcam) and then select camera from answering screen on n900. Had to disable skype and re enable it so that it fetched contacts again from server and now i have video call option on my skype contacts. (also remember to check in contacts option, upper menu, that video calling option is checked)
