The Electronic Frontier Foundation, which campaigns for freedom of speech and consumers' digital rights, has published Apple's iPhone Developer Program License Agreement. It's a document that isn't usually seen because application developers aren't allowed to talk about it publicly without permission. However, the EFF obtained a copy after making a Freedom of Information Act request after the US government – via NASA – published an iPhone app.
The highlights, according to the EFF, include a ban on making public statements about the terms of the agreement, a ban on using Apple's SDK to create apps that are distributed through non-Apple app stores, a maximum legal liability of $50 in damages and an acceptance that Apple can remotely disable apps at any time.
