As anybody who spends a great deal of time at a computer will be able to vouch, the timing of GTalk, Facebook, and other notifications received on a desktop, and the time it takes for that same notification to be pushed to a mobile device, are rarely in sync, with a delay of around three or four seconds occurring in extreme cases. However, a fix for this issue has been developed by a member of the XDA-Developers forum, and although it doesn't guarantee that notifications will arrive at the same time as they do on your desktop, it does make the retrieval of notifications much more streamlined.
