Roughly half a second after Apple began seeding Beta 1 of Firmware 2.2 to select developers, we began wondering: what we gonna get?! Firmware 2.1 handled the stability. Now we want some new features!
The usual suspects sound like a (still) broken record: cut/copy/paste, turn-by-turn GPS, video recording, Flash support, and MMS.
The recently "pushed" back include: Notification Server support to simulate multitasking for App Store apps (like instant messenger).
For us: unified inbox, email aliases, some Squirelfish-boosted Safari browsing, App Store refunds for duds, and pervasive landscape mode would be nice.
