Cerulean Studios has complained that a new Trillian instant messaging app, for the iPhone and iPod touch, has yet to be approved. The app was submitted over 60 days ago according to the company, but at last check is still winding its way through Apple evaluation. A steady stream of e-mails is said to have been sent, but met only with generic form letters, giving no indication on whether changes are needed or how much longer the company may expect to wait.
