Dropbox is buying the Mailbox mobile app and Gmail client for the iPhone. The details of the deals weren’t disclosed.

Mailbox would remain a separate app as the entire team joins Dropbox. Dropbox CEO Drew Houston told the WSJ that his company felt it “could help Mailbox reach a much different audience much faster.”

“Like many of you, when we discovered Mailbox we fell in love—it was simple, delightful, and beautifully engineered. Many have promised to help us with our overflowing inboxes, but the Mailbox team actually delivered.” posted Dropbox on it’s blog. “After spending time with Gentry, Scott, and the team, it became clear that their calling was the same as ours at Dropbox—to solve life’s hidden problems and reimagine the things we do every day. We all quickly realized that together we could save millions of people a lot of pain.”
