Is it going to be possible for someone to make a chat program and distribute it without downloading it from Apple? That gives apple the ability to decline it...
im pretty sure that they will allow developers who use the sdk to develop apps for the iphone to give there apps away thrue itunes as either freeware, shareware, or for purchase. so apps that you use on ur jailbroken iphone right now will probably be free when the sdk comes out to.
