As promised during the Let’s Rock event on Tuesday, Apple has released the firmware 2.1 update for the iPhone.
You can download it from iTunes. Changes include:
Fewer in call set-up failures and fewer dropped calls
Much better battery life
Less third party app crashes
Faster contact list loading
Less time to back up the iPhone
Genius playlist creation
Option to wipe the phone after ten passcode fail attempts.
More reliable email fetching, particularly from Exchange and POP
Better txting performance
More accurate 3G signal display
Repeat alert for smses for two additional times
I’m updating this from my iPhone using the WordPress app, on the bus from NYC-DC.
I definitely am looking forward to plugging the phone into iTunes and updating. Particularly getting faster backups after the 2.1 update.
