Good news, I hoped, but unfortunantly since the article states "Version 3.5", it means its the same update already available at dealers since early November (Version 3.5.1)! So don't get your hopes high, its a little improvement above version 3.2.2! There are already several threads discussing the upgrade.
As for warranty, in March 2012 a TSB (CSP-12M01) already extended the warranty to 4 years for Fords & 5 years for Lincolns, so does this extend it a further a one year?
