After numerous delays it looks as though AT&T will be launching their mobile TV service as early as February 5th according to Matt Kapko of RCRNews. MediaFlo, a subsidiary of Qualcomm that provides a similar service for Verizon customers will also provide all of the multimedia content for AT&T subscribers. To keep the spirit of competition alive and well amongst the carriers AT&T will have 2 additional channels reserved exclusively for their customers.
Here is the list of the 8 linear 24/7 channels
If there is a downside to this good news it would be that only the LG Vu a.k.a LG CU920 (similar to the Viewty) will be the only phone compatible with the new service.
