We knew it was coming, and it is here. Nothing too exciting in this new firmware update, but here is the only (minor) one I noticed: battery indicator next to iPhone in iTunes sidebar.

Also, Apple indicates "bug fixes" as usual. Sounds good to me.

To get this new update, just click "Check for Updates" when your iPhone is plugged in to iTunes. However, I would suggest that you not install this if you have hacked/unlocked your iPhone.
