Along with the official changes of yesterday's update, there are some unofficial changes that aren't good enough to make a bullet point on Apple's list. Which is weird, because some of these are huge.

  • You can now select different alerts for incoming messages:
    Settings -> Sounds -> New Text Message -> choice of:
    Tri-Tone (default), Chime, Glass, Horn, Bell, Electronic
  • International keys are available by holding down the letter key.
  • The iPhone mail application supports MP3 and .wav Attachments
  • includes the closed captioning abilities promised
  • enables a debug console for MobileSafari for web developers to find errors on their pages:
    Settings -> Safari -> Developer -> Debug Console [on/off]
  • breaks every 3rd party jailbreak -- the iPhoneDevWiki team will have to reverse-engineer the iPhone all over again
  • since the iPhone can't be jailbroken, there is no way to get 3rd party ringtones on the iPhone.

And just for the sake of posterity, after the break there's a readable version of Apple's list of official changes.

  • iTunes Wi-Fi Music Store
  • Louder speakerphone and receiver volume
  • Home button double-click shortcut to phone favorites or music controls
