Apple revealed several new features of iPhone OS 3.0 at WWDC today. One of these features is “Find My iPhone,” and it is only available to Mobile Me subscribers. However, the Mobile Me page includes a few other “Coming Soon” features that didn’t make it into the Keynote.

As I’m sure you’ve heard, Apple’s World Wide Developer’s Conference (WWDC) kicks off on Monday, and expectations are very high. Swirling around the web are lots of WWDC rumors guessing what Apple will do and anticipating with excitement the possible hardware announcement, but I want to spend a little time discussing what WWDC is really all about: Operating Systems.

Following rumors last week about AT&T offering contract-free iPhones to customers, Apple Retail Stores have now begun selling the devices without the need for a contract. You can now walk into an Apple store, purchase an 8GB or 16GB iPhone 3G, and take it home with you. What you do afterwards is up to you. You can also buy online, through the Apple website.

Will the “iPhone 3″ be the iPhone 3-D? It’s all rumors, of course, but after the yawner of Macworld Expo ’09, I think we’re entitled to a little speculation about the next version of Apple’s insanely popular device. Apparently the New York Post thinks so, too, since they’re just plain makin’ stuff up about what the next iPhone version could include.

I hope you like hearing about the Ocarina application for iPhone, because we here at Appletell are unlikely to shut up about it. The app turns your bleeding-edge-of-tech iPhone into a 12,000-year-old musical instrument, and is quite possibly the most offbeat musical application since Jared.

Wow, that was an unfortunate comparison to make.

Following is a video from Smule (makers of the Ocarina app), showing how you, yes you, can sit around with around $1,000 in hardware and groove to “Stairway.”
