According to the latest rumor posted, the upcoming BlackBerry 9000 might feature a front-facing camera for video calling. Because the 9000 features a 3G radio it would make perfect sense for it to have this. This new BlackBerry also features Wi-Fi and GPS. Guess we won't know for a few more weeks (if it launches at WES).
Personally we don't think this camera will be in the final version of the 9000, but maybe a variant of the 9000. Anyways stay tuned for more details.
