Works fine here.

Have you tried using port 143? Check the Incoming Mail Server setting  
on the iPhone. For port 143, there should just be a Host Name without  
":993" appended. ... I haven't tested with port 993. If you're  
synching email accounting with your desktop, you'll need to change it  
there and resynch - you won't be able to change it on the iPhone  
unless you setup the account directly on the iPhone.

Try ssldump. It's probably in ports. If not, you can get it from  
<http://www.rtfm.com/ssldump/>. Make sure you use "-k" with the IMAP  
server's key.
