Roger Cheng, writing for CNET: T-Mobile and Netflix are new BFFs. The primary beneficiaries of this new friendship will be subscribers to T-Mobile's "One" unlimited data plans, many of whom will get access to Netflix for free, T-Mobile CEO John Legere said on an "Un-carrier Next" webcast video on Wednesday. But the freebie only works if you have at least two T-Mobile One unlimited data plans (single line customers are out of luck). The free Netflix access arrives on Sept. 12. The alliance is just the latest proof that the worlds of video and mobile are colliding. AT&T is in the process of buying Time Warner -- home of "Game of Thrones" and Batman -- so it can own more of the content you watch, and has bundled HBO for free to some of its higher end wireless customers. Verizon has invested in creating short-form video geared towards younger audiences and a mobile video service called Go90.The offer is for the T-Mobile ONE plan with 2+ lines.
