I like the notification bar a lot, but have a few issues with iMessage in particular. My buddy has a iPad and iPhone4 with iOS5. iMessage doesnt group his messages together. I get some a group of messages from his iPad and a group of messages from his iPhone. It doesn't specify which account is which in my messages, so now I can't really tell which one to use for his iPad/iPhone. Also, In the notification bar, why doesnt the icon for iMessages blue. It would be nice to see green icon for an ordinary SMS and a blue icon for a an iMessage.
