Apps are slowly starting to get updated for Windows Phone 8 in preparation of November 9th when the Lumia 920 and 8X go on sale. Today the official Twitter app has received an update that adds a few Windows Phone 8 features.
The most notable is that the app is now compatible with higher screen resolutions. No more black bar up top! The other new addition is the double wide tile size. We can’t tell if the app is using fast resume or if they just removed the splash screen, but either way it opens very fast now. The only thing missing is lockscreen notifications. Still, this is a very good update.
EDIT: It appears that the app is using fast resume If you back out of the app it restarts and you see the splash screen, but if you leave the app via the Start button and then tap the tile on the start screen it opens right back up. Nice!
