We don't highlight many applications on MobileTracker, but we got to play around with one called Qix and had to share. It's only for Symbian phones and has to be installed by the carrier (you'll see why in the video), but it presents a whole new way to use a phone. It's like Quicksilver (Mac) or AppRocket (Windows) for a phone.
After using it for some time we became big fans and really wish Qix was available as a user-installable application. It has undergone testing with Virgin Mobile but is not widely available at this time.
