Apple to Preview iPhone OS 3.0 Next Week

— -- Apple sent out invitations Thursday morning to a media preview of iPhone OS 3.0, the next generation software for the device. The invitation doesn't give any clues of what the new operating system will feature, but Apple says that this will be an "advance preview of what we're building." The media event will be held March 17 at the company's Cupertino, Calif. headquarters at 10 AM PST (1 PM EST).

Next Tuesday's preview comes about a year after iPhone OS 2.0 came out. Many of the recent rumors circulating about a new iPhone have focused on a hardware update rather than a software update. While a hardware update is intriguing, there are many software-related features iPhone users have been anxious for since its debut.
