Once solely slated for the Chevy Volt, the OnStar MyLink smartphone app has gained considerable ground -- last July, GM expanded the iPhone and Android remote domination over your horn, door locks, and real-time data to every 2011 automobile, and now it's reaching back through time to activate fourteen vehicles from 2010. As you'd expect, that's mostly a smattering of SUVs and crossovers like the Cadillac Escalade, Buick Enclave, GMC Yukon and Chevy Avalanche, though the Impala will also get the goods, and if you live in the lap of low-end luxury, you may be able to listen to Facebook updates on your 2010 Cadillac DTS or Buick Lucerne.
