AT&T's MediaFlo Mobile TV service we told you about in March is ready to roll. Accessible on the Samsung Access and LG Vu handsets which are set to go on sale May 4, AT&T customers will pay about $15/month for unlimited mobile TV access. The service will have at least two exclusive channels including the Sony PIX movie network as well as 10 major broadcast networks including Fox, plus live CNN content. The LG Vu will cost you $300 after a $100 rebate and 2 year plan and the Samsung Access will put a $200 dent in your wallet, once again after a $100 rebate and 2 year contract. Check out the service in action in the video above.
