iPod touch users got first crack at the highly-anticipated 2.1 firmware update yesterday despite Steve Jobs' comment that it wouldn't be available until Friday. Touch users noticed the update appearing in the update panel of iTunes late yesterday and Patrick McCarron grabbed a screen showing the new features.
Features listed in the 239MB update include:
Genius playlist creation
dramatically reduced time to backup to iTunes
improved email reliability, notable fetching email from POP and Exchange accounts
faster installation of 3rd party applications
fixed bugs causing hangs and crashes if you have lots of 3rd party applications
