http://www.engadget.com/2008/08/07/iphone-hacker-says-the-device-calls-home-to-apple-allows-apps/ I guess apple's trying to sneak more stuff behind is? I mean I guess I can understand why they would do this, they're allowed to.. but anyways still seems a bit sneaky to me. *Prepares to be spammed that there is another topic regarding this.. I swore I searched for others! x.x*
I've heard of medical apps and such running for like $100+ I think, but I don't think apple would let anyone sell apps for $1k..
There was a $1000 app it was called I'm Rich. from what I have read 8 people have bought it. http://www.iphonefreak.com/2008/08/8-people-bought-the-1000-app-im-rich.html
apple can't remotely disable apps this blacklist is for CoreLocation, and can block apps on the blacklist from using the CoreLocation API, so those apps can no longer find out where you are its incase any apps start abusing the location based awareness of the iphone
