Whatsapp New Version - Holo redesign, expandable JB notifications
What do you think?
I personally think it was about time we got an update for our phones, the new design is on par with holo android design guidelines and the new expandable notifications blend perfectly into the phone.
Also, if you look at the iphone version of the app it still looks like the old version for android.
