Another app getting an update today with some Jelly Bean compatibility is SwiftKey Keyboard. While it worked on Jelly Bean before, the update did introduce a few bugs and this release serves to squash those and a few others such as predictions not appearing in popups as well as some UI issues that were happening to some folks. You'll find the update waiting for you in the Google Play Store, download link below if you're new to the app.
