My favorite (and arguably the most useful) iPhone application is Yelp. Yelp integrates seamlessly with Google Maps, displacing the need for the in-car GPS system.
A few other great apps for the iPhone are:
- Backgrounds - a great selection of photos to spice up your background
- aNote - a simple app to take notes
- Echofon - my favorite app for Twitter
For social networking and dating, the latest version of the Facebook app now includes push notifications. And the Match.com application offers a simple interface that has yet to be imitated or bested by eHarmony.
