Free, cloud-based streaming music service Spotify, which is unfortunately still available only in Europe, has released a new version (0.4.3) of its desktop client. The new version introduces a number of improvements centered on music management and social sharing.

The most important new feature is called the Library, which lets you import your own music into Spotify. Even better, you can copy music files to your mobile wirelessly, instead of having to connect via a USB cable. You can also star items in Spotify, effectively tagging your favorite tracks for inclusion in a special subfolder.

As far as social features go, Spotify now offers Facebook integration. You can connect to Facebook in the application, which will instantly connect you with your Facebook friends who have selected that same feature. You can manage these from the new People sidebar at the right of the screen. You can also publish your Spotify profile to the web, send tracks directly to friends via the Inbox folder and showcase the music you’ve been listening in your Facebook feed.

Check out a video highlighting some of the new features below.

Before the iPad even landed, pundits picked apart its palpable flaws, one of which is the device’s lack of a built-in camera. If you own both an iPhone and an iPad however, you can jimmy rig the former into a wireless iPad camera for $.99.

All that you need to take photos on your iPad is two apps,CAMERA-A [iTunes link] for the iPad for $.99 and CAMERA-B[iTunes link] for the iPhone 3GS (free).

To take iPad photos wirelessly from the iPhone, pair both devices via bluetooth or make sure they’re on the same wireless network. Then open both apps. You’ll immediately notice that what your iPhone camera sees is mirrored on your iPad’s screen. Simply use your iPhone as the lens, click the photo button on the iPad and your snapshot will be saved to your iPad.

If it sounds complicated, rest assured, it isn’t. In our test trials the iPhone functioned flawlessly as a wireless camera and with each snap we were able to save the photo to the iPad’s photo library (see my sample photo below).

It may not be the most ideal iPad camera solution, but it’s certainly one that works. Try it out for yourself and let us know what you think in the comments.
