It's actually every 15 minutes with email "polling."

"Push Email" is actually the "idle" function of the IMAP email protocol. It allows a connection between the BIS server and the mail server to remain in an open state so that the BIS server "sees" new email right away.

fyi: aol/aim, hotmail, yahoo, gmail are all capable of this.

I can't remember having this many BIS problems with the Curve, or other BB's i have had.
