Sprint's quietly gone and refreshed their mobile portal, launching a new home page that should already be available on 40 or so of their handsets.  Working with tech partner ChangingWorlds, Sprint developed an adaptive home screen that's unique for each user - the catch is that the carrier is mining your use history for the data upon which your special home page is built. 

Most users likely don't care if they're giving up some privacy (well, you're not really giving up anything new - Sprint already knows everything Sprint customers do on Sprint devices) in exchange for a fancy new custom portal.  The big question will be how well the thing works.  I'll fire up my new Treo 800w's Web browser and see what I get - Sprint customers, check out your new home page and report back: How're you liking the new look?  Or are you even seeing it yet?  Click on through for the official press release.
