MediaFLO is about to cut loose for AT&T customers and we've got video to prove it. After the break you'll find Mobile TV running on LG's new $300 (2-year, after $100 rebate) Vu, one of just two Mobile TV compatible handsets launching on AT&T May 4th -- the other being the $200 (2-year, after $100 rebate) Samsung Access. Performance looks reasonably snappy when scrolling through the channel guide although some of the exclusive PIX and CNN Mobile Live content is not yet available. S'ok, AT&T has three more days to throw the big blue switch on the broadcast TV service which includes a $15/month unlimited Mobile TV access plan. Hear that Verizon? AT&T's about to step all over your portable TV game in the US market.
