alison kosik has a new security feature that may prevent apple picking. >> i'm used to getting parking tickets from the new york city police athan getting software advice but now new york finest are asking us to go ahead and download that ios 7 now. the nypd are big fans of the apple operating system because it has activation block and the new feature actually forces you to enter an apple i.d. and password before you can turn off the find my iphone app so this would be a deterrent for thieves. they are encouraging everybody who has an iphone to download the operating system so they spend less time tracking down iphones and more time for writing parking tickets. >> i would prefer that.
