Get 1GB More Space in Dropbox with Mailbox iOS App
Want to get an extra 1GB of storage for your Dropbox account? Just link your account up with the free iOS Mailbox app.
After installing Mailbox (which requires a Gmail account), go to Settings, Dropbox, add your account and you'll get an extra 1GB of space. If you've already linked the two together, unlink and relink them to get the free 1GB. Besides the extra storage, linking your account also lets you attach files directly from your Dropbox folder into an email.
Mailbox, formerly known as Orchestra to-do, is a gesture-based Gmail app which helps you easily process your email by swiping left and right. It was acquired by Dropbox for a reported US$100 million in March this year.
