iPhone firmware update 2.2 is available... now!

Apple has released iPhone software update 2.2 this morning - the latest firmware upgrade for its handset.

You can get it by firing up iTunes and clicking on the Check For Update button on the iPhone screen. It's a whopping 246.4MB download, mind.

There are no specific improvements for gaming, at least judging by the feature list released by Apple. What you do get is:

• Enhancements to Maps (including Google Street View, public transit and walking directions, the ability to display the address of dropped pins, and share your location via email).
   
• Enhancements to Mail (including sorting isolated issues with scheduled fetching of email, and improved formatting of wide HTML email).
   
• Improved stability and performance of Safari
   
• Podcasts are now available for download in iTunes application (over Wi-Fi and cellular network)
   
• Decrease in call set-up failures and call drops
   
• Improved sound quality of visual voicemail messages
   
• Pressing the Home button from any Home screen takes you to the first Home screen
   
• Preference to turn on/off auto-correction in Keyboard Settings

At first glance, the update appears to be for iPhone and iPhone 3G only, rather than iPod Touch.
