IMO nothing about Video vcast. but Vcast music is cool. they have a huge selection.

VCast basically enables you to have unlimited access to the internet through your phone. Unlimited in that it doesn't take from your allowance minutes. It also enables you to view/download/stream video clips from several avenues such as ESPN, MTV and Comedy Central; to name a few. Lastly it makes all other web based applications from your phone airtime free as well...such as VZ Navigator

I use it to watch clips from the daily show and colbert report. It also comes in handy to get my hotmail without using airtime.
