YouTube videos will be viewable on cell phones for the first time under a deal with Verizon Wireless, which will also allow users to upload videos shot with their camera phones. The partnership to be announced Tuesday marks the first big distribution deal for YouTube since the young video-sharing website was acquired earlier this month by Google Inc. for $1.76 billion. The mobile YouTube service, to be launched in early December, will be offered for no additional fee as part of Verizon's V Cast service, which costs subscribers $15 per month or $3 per day. The companies declined to provide an exact launch day, saying the technologies being employed are still being tested.
