Apple yesterday unveiled iPhone OS 3.0 which boasts over 100 new features. Unfortunately, we will have to wait until the summer to get our hands on the new iPhone operating system. To tide you over until then, take a look at 10 iPhone 3.0 features that look the most promising.

P2P Connectivity: No, this isn't file sharing. But as part of Apple's improved Bluetooth support, applications will now automatically search for other iPhone devices in close proximity and let you interact with the user. This will have a variety of uses including gaming and information sharing programs. Since P2P operates over Bluetooth no wireless Internet connection is necessary, and you can use the feature anywhere. You may not be up for a leaf trombone duet you see in the picture, but quiet games the kids can play together on road trips might just come in handy.

GPS: Turn-by-turn GPS is coming to iPhone 3.0. According to Apple, many developers requested this feature and we know that many of you have been waiting for this as well. The official capability is now in place, all you need now are the apps.
