Yes it is. Another half of problem: sometimes now-free SIM tray self pops up and, yes, this causing disconnect N9 from mobile network. Interestingly that after pushing tray in, phone also connects to network without rebooting OS. Ok. But I think, I may lose microSIM and it's time to wear something on N9.
What Case of Perfection for N9 in addition to the standard? Images, photos, history threads, holywars? Thanks!
