Honestly, that ruling seems to be more "You can't get around the arbitration agreement you signed by joining a class action", which is good law. The problem, which wasn't the issue in this case, is the validity of mandatory arbitration agreements as a whole for consumer products, and that's a much bigger and entirely different battle. Probably one that needs to be fought in the legislative arena, not the courtroom.
Anyway. If I had an iPhone 4 with whatever the current version of iOS is, and an update was put out that was compatible with my phone, can I plug in and sync and do all that shit you have to do to manage an iPhone without ever accepting the update? It doesn't really matter, adding "you consent to being tracked" language to your EULA with a hotfix is shitty no matter what, but I'm curious.
