Just out today is a new application for the Blackberry called, RSVP. RSVP is an application that streamlines the process of responding to phone calls and SMS messages. RSVP enables you return missed calls and place calls without having to navigate through multiple menus or answer multiple choice dialogs.

Click and hold the trackwheel to see menu of alternate contact numbers. Select the alternate number from menu to call immediately.

You can launch important BlackBerry applications such as Broswer right from RSVP.

RSVP can also act as your primary application for phone and SMS services on your Blackberry, with the ability to compose messages from your Address Book in addition to responding to recent messages.
