A quiet BlackBerry Internet Service upgrade has been rolled out that according to many is resulting in much quicker e-mail delivery over IMAP. Traditionally, only those on BlackBerry Enterprise Server would get their e-mail pushed to their handset instantly, and BIS users had to wait 10-15 minutes for delivery. Now anyone getting their BIS e-mail via servers that support IMAP IDLE will receive messages in real-time as the standard was designed to provide. It’s great to see the upgrade, especially for BIS users who have had less-than-stellar delivery times, but you have to wonder why it took so long for IMAP IDLE to be supported.
