Although this years Macworld Expo keynote address didn't include any major iPhone-related announcements, a few important feature enhancements were introduced:
- iTunes over 3G Pushing ever-increasing data over the AT&T network, Apple is now offering the ability to push iTunes music files over 3G connections. Previously, the iTunes mobile app could only download songs over WiFi. First-generation iPhone owners are still out of the loop. This functionality requires no software update and works right now.
- Keynote remote control A new application, available through the App Store, allows users to control Keynote presentations from the iPhone. Priced at $.99, the app lets you advance slides via a Cover Flow-like interface.
- iPhoto integration Picturs taken on your iPhone and uploaded to iPhoto '09 include geotagging information. This lets you automatically organize photos by place and recognize landmarks in major cities. Slideshows from iPhoto also now work on the iPhone.
