Apple’s iPad is shown after it was unveiled at the Moscone Center in San Francisco. Apple Inc. said Thursday that it will publish the guidelines it uses to determine which programs can be sold in its App Store, the exclusive place to get apps for the iPhone and iPad, giving software developers more leeway in how they create applications for iPhone and iPad. The move likely is to benefit Adobe Systems, whose software had been panned by Apple’s Steve Jobs. The company said earlier this year it would not accept applications made with tools from other companies, including Adobe.
