Have a Blackberry 8707v to play with for a while, and got the email side of it set up - almost. While I can make it talk to my Exchange server (and services like Gmail) without problems, the email client doesn't seem to understand the IMAP NAMESPACE feature. I can't see any server folders besides the top level one. Have googled, RTFM'ed but I can't find anyway to add the NAMESPACE root prefix to the email client.
I use Courier-IMAP here, which puts the IMAP folders underneath INBOX.
Workarounds, anyone?
