iPhone OS 4.0
Features listed here: http://en.wikipedia.org/wiki/IPhone_OS_version_history#4.x:_Fourth_major_release_of_the_OS
Some handy new features.
Mutli-tasking is obviously the major talking point and makes subscription apps like Spotify far more attractive.
There's probably some hidden gems in there too such as the Birthday Calendar - Calendar is currently shite for birthdays.
Excitied?
Ashamedly, I am.
