Waze is a social GPS navigation app that offers ridesharing and gaming.

People who own an iPhone have the possibility to turn their phone into a GPS device thanks to a slew of apps. Among them is Waze, an iPhone app that provides both turn-by-turn GPS navigation but also adds a gaming element that let drivers share their position and time, or alert one another to speed traps, construction zones and traffic tide-ups. The utilitarian nature of the app aside, Waze has always been a fun and useful way to get free turn-by-turn directions right at your fingertips and share very valuable traffic and travel information with other drivers and friends. Now, the app has updated to add groups and social features designed to help commuters and potential carpoolers find a ride and share empty space in their vehicle. Among some of the app's new features are the ability to create "driving groups," or groups of people who all commute from the same area every day, or for fleets of drivers who drive together from place to place. For instance, the app is useful for commuters looking to organize a ride-sharing program at their workplace, or for a group of friends taking multiple routes on a road trip to see which route is fastest. Additionally, groups can be used for common interests as well as activities, like drivers sharing the cheapest gas stations in their area, affordable parking in popular downtown neighborhoods etc.
The app also offers drivers special achievements for performing certain actions like sharing information or starting a group. The app is still free and the new version is available now in the iTunes App Store.

Garmin Oregon 550 is a hand held GPS that can snap photos.

Garmin's Oregon 550 combines rugged outdoor touchscreen navigation with a 3.2 megapixel digital camera. Add high-sensitivity GPS, barometric altimeter, 3-axis electronic compass and microSD™ card slot. The result? A multipurpose device that will make your biggest adventures even more memorable.
According to the New York Times, the Garmin’s $500 Oregon 550 can snap photos and geotag them.

The Oregon 550 is a waterproof hand-held device that’s perfect for hikers, bikers, backpackers and boaters. Its camera offers four-times digital zoom and 850 megabytes of internal memory; it also includes a microSD slot for additional photo storage. Every photo is automatically geotagged with the precise location where it was taken.
The Oregon 550 has a three-inch touch screen that Garmin says is readable in bright sunlight, and also includes a built-in compass. The device employs a barometric altimeter that can help you determine altitude (and, Garmin says, be your own weatherman by plotting barometric pressure to predict weather conditions).
The device comes loaded with a worldwide base map and enables you to add maps (via the microSD slot) that meet your navigational needs, including street maps that offer turn-by-turn directions and maps for rivers, lakes and oceans.
Garmin also unveiled the Oregon 550t, a $600 version of the navigator that is loaded with topographic data for the continental United States and a worldwide base map with shaded relief.
