I just upgraded and jailbroke to 4.1. I know that 4.2 is coming up soon. Is there any reason to upgrade to 4.2 other then AirPlay or Printing ability? Are there any other features that would make anyone want to upgrade and rejailbreak to 4.2? Are there any performance increases? Or is it just Airplay and Printing? What would be the main reason for anyone to upgrade from 4.1 to 4.2? Any opinions would be much appreciated. Thanks!
