I'm using a D6603 running 5.0.2 and I've got the close all apps button. The weird thing was that after it did what seamed like a whole day of OTA updates I plugged it into my PC and it installed the connection software and did one more. Not sure if this is simply only available in the UK, over the Internet, or I have some freaky hybrid, but that's where I'm at and how I got there..
