FiftyThree's shipping out its first Pencil styli early this December, but before you can work its sketching magic, the firm's Paper app will need the appropriate updates. Good thing the company's released those changes today, because waiting on a software upgrade to use new hardware breeds a special kind of frustration. As you'd expect, the refreshed app comes with the features FiftyThree promised when it announced the $50 tool, including palm rejection to avoid accidental hand marks on sketches. There's also the erase function that activates the device's built-in eraser, and the blend feature that lets you use fingers to blend colors and edges. Based on the firm's Twitter posts, it's sending out emails to people slated to get their Pencils soon, but those who've only just ordered one have an excruciating three-to-four week wait ahead of them.
