While the U.S. Postal Service may be cutting back, there’s a new iPhone app that could soothe your senses–once your name is called. Mailbox is a free application that turns your iPhone inbox into more of a to-do list, letting you check off messages with a series of speed-based swipes. A fast swipe to the right archives a message; a slow swipe deletes it. Swing your finger to the left and it gets the “snooze”, coming back to your inbox at a later time. As we mentioned, you’ll have to wait for it. As it stands now, you gotta download the app to reserve your spot in line; a line some 250,000 people deep.
