1.1.3 was great 1.0.1 had two problems till now:
1) As i rebooted my phone this loading circle of the N9 appeared and didn't go away until i restarted the phone again.
2) As I browsed in the Web the N9 turned off and as i restarted it, it asked the phone code but not the pin code of my Sim.

Also i had the bug 749 (the reason why i changed to this version).
