Nokia is working on some new applications for mobile phones.  Check out their site, www.widset.com.  The application lets you add mobile widgets to your phone to track blogs, news feeds, online communities, etc.  Currently it works with Flickr, Digg, Engadget, Meetup, Simply Hired, and many others.
 
While I was out in Vegas in January for CES I got to meet the co-founder of Soonr.  The application lets you access any files and programs on your home computer through your phone.  It also lets you designate shared files that others can access.  The power of the application is that it can easily access programs like Skype or your Outlook over almost any phone.  It could also be a great tool for sales people who need access to materials or want to share designated files with prospects.  The company is backed by Intel Capital and the application is currently free.  www.soonr.com
