Apple has officially began accepting iPad app submissions after developers received the following email from Apple earlier today. Also, below the email you will find some screenshots from our friends at 9to5Mac showing some of the recent updates made to iTunes Connect, specifically the interface for submitting iPad apps. If you are a developer interested in developing for the iPad or already have an app in the works, you will most likely be interested in taking a look.
