I am a huge fan of SugarSync and use it to backup and sync all of my computers. Their BlackBerry app has left me wanting for more features but it looks like they have not forgotten about us. They just let us know that they have released a new version of their BlackBerry app which adds the following new features:

• Music Streaming: Now, stream all your tunes from the cloud. Even cooler – you aren’t limited to one song at a time. Just start playing the first song in an album and SugarSync will play through the complete album – even in the background. Whether you’re traveling away from home or commuting, SugarSync gives you all your music at your fingertips.

 

• Email auto-complete: This is a true convenience. Instead of having to type in a complete e-mail address, just start typing and we’ll fetch it for you from your address book. So much better than cut-and-paste or manually typing out the entire e-mail.
• Bug cleaning. No software will ever be bug-free, but we continue to strive to make your experience as easy and smooth as possible.

I think the music streaming is the coolest feature of all though I wish it would let you select a playlist or even better start caching a playlist on your BlackBerry. You can get version 1.5 of SugarSync in app world at this link.
