We've been hearing plenty of buzz around YouTube Mobile over the last few weeks. In early November, Mashable reported that talks between Verizon and YouTube were in an "advanced stage" - now we have a deal, with YouTube set to announce today or tomorrow an agreement that delivers clips through Verizon's V Cast service. Although YouTube have been promising that YouTube Mobile would be launched within a year, this deal will come to fruition much faster: you can expect the service to launch next month. Users will be able to view select YouTube videos on their Verizon phones, and upload clips from a Verizon phone to YouTube. It's thought that other carriers will jump on board very soon. Verizon, meanwhile, already has clips from MTV, ESPN, and ABC News, and the V Cast service costs an extra $15/month.
