OK, I can understand some unknown developer who has a few downloads per day not worrying about updating their app to have full 4" screen support. BUT whatsapp? Isn't it one of the top5 apps in the store? Man, every time I switch from Messages to Whatsapp I'm like wtf man?!? This is tiny! Emailed them but didn't even care of writing back. Point of this thread being... Does anybody know something I missed? Did they make any kind of announcement?
