Apple has just released iPhone, iPhone 3G and iPod Touch firmware 2.2. The software update contains many of the much anticipated changes including Google Street View, public transit and walking directions, and over-the-air podcast downloads via the iTunes app.
The update also includes numerous fixes including added stability in Safari and fixes for Mail.
This is the official release notes:

Products compatible with this software update:
• iPhone 3G
The update also upgrades iPhone 3G’s modem firmware (baseband). According to iPhone Dev Team you should NOT upgrade your iPhone 3G to 2.2. This will remove the unlock on your iPhone.
If your iPhone or iPhone 3G is jailbreaked, you should seriously reconsider upgrading too. The upgrade will remove the jailbreak feature. If the jailbreak doesn’t matter to you, you can safely upgrade your 1st generation iPhone.
If you plan on using the soft unlock from iPhone Dev Team for iPhone 3G when it’s released in the very near future, don’t update either.
Update: iPhone Dev Team has just written a post recommending those that want to soft unlock NOT to upgrade their iPhone 3G. The post also explains why you shouldn’t update.
Tethering in cellular wireless is the connection of a non-mobile device (e.g. desktop computer, notebook computer, laptop computer), to a mobile device (e.g. cell phone, PDA) for the purpose of wireless Internet access by the non-mobile “tethered” device.
