Rumor Mill: Verizon launching BlackBerry push-to-talk service

Verizon Wireless has released a new push-to-talk service for users of Research In Motion's BlackBerry smartphones, according to the blog Boy Genius Report.

The service, which has been whispered about for some time, is now available for free to download, according to the blog, but it will cost $5 per month. The push-to-talk service will give users unlimited nationwide calling to other push-to-talk devices on Verizon's network. Representatives from Verizon declined to comment.
