The BlackBerry Bold 9800 slider seems to be stealing all of the headlines away from Froyo, the new iPhone, and just about every other device today.  This time we've got a nearly four minute video of the phone showing several new features of BlackBerry OS 6 in action, including using mobile YouTube.  The OS does seem slightly buggy, but hopefully those issues will be ironed out by the 9800's alleged release next month.  An important piece of the video comes right at the beginning when the user starts up the device and we are shown an AT&T splash screen, confirming that the Bold 9800 is fated to compete with the new iPhone on AT&T next month.  Has this video made you more excited for the Bold 9800 slider?
