iPhone OS 3.1 (IPSW) Available for Download

iPhone OS 3.1 was actually the announcement that kicked off yesterday’s iPod event at the Yerba Buena Center for the Arts in San Francisco. Steve Jobs bluntly described the new software as packing a bunch of nice features in it, as well as a few bug fixes. The Apple website, however, reveals that there’s quite a lot to be had with the update that’s free for iPhone owners, and costs just $4.95 for iPod touch users.

First off, the Genius Recommendations for Apps is a new feature in iPhone OS that allows users to get recommendations for apps they might like based on apps they’ve already downloaded. Based on similar algorithms, Genius Mixes has iTunes automatically create mixes based on what’s already in a user’s library. The ability to wirelessly Download Ringtones has also been added, along with the one to organize apps from the iTunes interface (requires the latest version of the desktop application).

“The free iPhone OS 3.1 Software Update includes some great new features, as well as all the features from previous updates,” Apple says on its website. “iPhone OS 3.1 gives you Genius recommendations for apps, lets you download ringtones wirelessly, offers a new way to organize apps on your iPhone, and more.”

“And more,” indeed. While iPhone OS 3.1 also includes the features from iPhone OS 3.0, many of the functions listed below are completely new to iPhone and iPod touch. So here’s the full breakdown. “iPhone OS 3.1 also includes these features and updates,” Apple says.
