The official CNN app from Nokia has been updated. Version 1.5.1 comes without a changelog (no change there then - pun intended), but we've noticed speed improvements and optimisations being applied to better the overall experience. Loading the app is much quicker and it seems to do a more efficient job pulling content down.
If you're into all the latest headlines and whatnot, the CNN app is well worth checking out. It's available for all Lumia Windows Phones as a Nokia exclusive. You can download the official CNN app from Nokia on the Windows Phone Store, using a Lumia handset to access the Nokia Collection of apps.
