This is a nice upgrade loaded with use features that include:
- Google Maps Walking and Public Transit Directions
- ITunes Store Podcast Downloads
- Apps Store sorting options
- The ability to disable the annoying Auto Correction keyboard setting (Setting > General > Keyboard > Auto-Correction Off
- Pressing the App Home Button is suppose to return you to the Application Home screen with this release but this feature did not work for me.
Overall, a very nice unexpected full featured iPhone update. Great job Apple iPhone Dev Team!
