Just connect your iPhone to your computer and click “Check for updates” in iTunes.

Here’s what Apple has to say about the update:

This update contains many bug fixes and improvements, including the following:

  • Enhancements to Maps
    -Google Street View
    -public transit and walking directions
    -display address of dropped pins
    -share location via email
  • Enhancements to Mail
    -resolved isolated issues with scheduled fetching of email
    -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

I’m downloading and installing the firmware right now. It’s a 246MB download and who knows how long it will take to install but I’ll update here with my first impressions after I spend some time with it.

Update: Google Street View blows my mind, but since I currently have what we in the business like to call “the old iPhone” EDGE isn’t fast enough to really make Street View worth it for me in real world situations. Walking directions and public transit directions are great if that’s what you need. The visual changes to Safari look odd at first glance but make a lot of sense when used for a few minutes. Podcast downloading works very well, searching and browsing podcasts is really easy and this may actually give me an excuse to open the iTunes app from time to time. One feature not talked about by anyone is that now you have the ability to delete podcasts, which is useful to me.

I don’t see the current implimentation of podcast downloads changing the way I personally deal with podcasts but it may let me make it a couple more days without my computer and still be able to get my podcast fix.
