It's a good day for next-gen network news, apparently -- first Verizon promised to bring its 4G network to 30 NFL cities by the end of the year, and now AT&T's John Stankey says its LTE network will arrive by mid-2011. Trials are already underway in Baltimore and Dallas, and Ma Bell's pulled some $700 million out of the kitty to fund the buildout, with investment scheduled to go "far beyond that" next year. On top of that, AT&T is also working to upgrade its backhaul connections to current HSPA 7.2 3G sites and is planning to upgrade the vast majority of its 3G sites HSPA+ for real-world 7Mbps 3G download speeds sometime
