Over this past weekend, BlackBerry customers received a little treat if they're using Gmail or Yahoo! Mail accounts. RIM updated their BlackBerry Internet Service (BIS) for what should be all service providers in North America from 2.1 to 2.3. With RIM's latest endeavor to reach a common ground for BES (BlackBerry Enterprise Service) functionality for the BIS subscriber, customers should now be rocking two-way wireless synchronization of deleted emails, auto forwarding from BIS email addresses, as well as read / unread message counts. From what we can tell, the upgrade went smooth with no issues -- which is exactly how BlackBerry users like it.
