Apple has finally approved a Twitter iPhone app despite sometimes presents naughty words, CNET reports. The company intially rejected Tweetie 1.3 due to an offensive word appeared in Twitter’s Trends data.

In an e-mail earlier Tuesday, app developer Loren Brichter said Apple quoted this part of the company’s guidelines as a reason for the decision:

“Applications must not contain any obscene, pornographic, offensive, or defamatory content or materials of any kind (text, graphics, images, photographs, etc.), or other content or materials that in Apple’s reasonable judgement may be found objectionable by iPhone or iPod Touch users.”

However, Apple relented Tuesday, according Brichter.
