Invites have begun to trickle out for a March 17th Apple event, at which they’ll be debuting iPhone OS 3.0. It has been about 8 months since the release of OS 2.0, and 6 months since Apple missed their self-imposed deadline for push notifications for background applications.

Will background apps be addressed? What about the oft-griped about lack of copy and paste? Will they polish up all those little things we still can’t stand? Tune back in on March 17th at 10 am PST to find out.
