Update: The iPad version is now out on iTunes as a universal app.
The promised iPad version of the email management app Mailbox recently acquired by Dropbox is launching today, offering essentially the same user-interface as the iPhone original, with the addition of a reading pane to the right.
In an Interview with The Next Web, co-founder Gentry says that an Android version is in the works, but with no launch date specified as yet.
Interestingly, the company declined to give any take-up or retention figures for the iPhone version of the app.
