The Amazon Appstore launched Tuesday with an offer of one free app a day, kicking off with the ever-popular Angry Birds for Android. Bloomberg reports that Apple filed a complaint March 18 accusing Amazon of trademark infringement and unfair competition.

In a separate case that has been pending since 2005, a federal judge ordered Steve Jobs to testify in a complaint that alleges Apple ran a music-downloading monopoly. Jobs, who has been on medical leave from the company, will be required to testify for only two hours, the judge ruled.

Meanwhile, a new app at Apple’s App Store is angering gay rights groups. The App Store, which has felt heat for rejecting some apps, features a free app from Exodus International, a ministry that teaches that homosexuality can be overcome through a relationship with Jesus Christ.

The app has more than 900 reviews in the App Store, many of which accuse Apple of supporting bigotry. Truth Wins Out, a gay rights group, has started a petition to request that Apple remove the app. It has received more than 130,000 signatures and points to Apple’s guidelines for rejecting apps: “14.1 — Any app that is defamatory, offensive, mean-spirited, or likely to place the targeted individual or group in harms way will be rejected.”
