Sure, it can do it in two ways: open several connections to imap server 
(one per folder) or periodically change current directory and get 
changes. But any of this solution will eat battery very fast, 
proportionally to count of folders to check.
I think that battery life is the reason, why this feature is not 
implemented in iPhone. It will use only one IMAP connection.
