The next update to RIM’s BlackBerry Internet Service protocol used for data access on the BlackBerry device lineup will feature full Google and GMail sync after years of dependence on third-party tools and applications for incomplete synchronization between device and accounts according to a leaked internal PDF.
BIS 3.0 will allow message status changes made in both Gmail and on the BlackBerry to by synchronized in both directions instead of the one-way sync found in version 2.8 of the protocol. The updated protocol is expected to be rolled out by the manufacturer in March, with no availability timeframe for carrier deployment available at this time.
