If you haven’t heard about Mailbox then you should check this link: http://www.mailboxapp.com/
I downloaded the app on 2/22 and after 28 days I am still in the line, waiting for more than 60,000 people in front of me. Would it worth the wait? I certainly don’t know until I can get the app to work on my iPhone. Time will tell.
And here I am, waiting.
