NEW YORK (AP) - Apple Inc. gave software developers on Thursday the guidelines it uses to determine which programs can be sold in its App Store, yet it reserved for itself broad leeway in deciding what makes the cut.

The move follows more than two years of complaints from developers about the company's secret and seemingly capricious rules, which block some programs from the store and hence Apple's popular iPhone, iPad and iPod Touch devices.

The guidelines go some way toward addressing those complaints and broadening the discussion about Apple's custodianship of the App Store, but they leave much for the developers to figure out.

"We will reject Apps for any content or behavior that we believe is over the line. What line, you ask? Well, as a Supreme Court Justice once said, 'I'll know it when I see it'. And we think that you will also know it when you cross it," the guidelines say.
