The humble unlock screen gets ever fancier, and Nokia Bubbles is one of the fanciest we've seen yet. Like a variety of aftermarket lock screens it enables you to control your media player or initiate calls before you even unlock your handset, but does so in an interesting way. You just grab the bubble for what you want and drop it on what you want to do. A simple unlock entails dragging the key onto the lock, and if you have a missed call you can grab that person's bubble and drag it to a phone to call them right back. Grab the music bubble to go straight to the music player and, well, you get the picture. Okay, so it's not quite as much fun as playing Puzzle Bobble, but it is ever so slightly more useful. Check it out in the video below, or go ahead and give it a download if you're on Symbian.
