The partnership will include enhanced integration of Yahoo! Mail accounts for BlackBerry users, including enhanced real-time delivery of e-mail messages to their handhelds from their Yahoo! Mail account, in addition to enhanced wireless synchronization of sent and deleted items and read/unread message status. The ability for BlackBerry users to wirelessly import, modify, and synchronize their Yahoo! Address Book and Yahoo! Calendar will also be a goal of future development. RIM and Yahoo! will also look to bring Yahoo! Messenger to the BlackBerry, in addition to making Yahoo! Search available through one-click on the BlackBerry main screen.
