SugarSync for BlackBerry has recently been updated to v2.0. In addition to increasing the performance and reliability, SugarSync revamped the user interface with an improved layout and the addition of tabs for easier navigation.  They also simplified sharing by utilizing your native email account for file and folder sharing along with giving users the ability to copy public links and paste it into any application or email message.
