Earlier we posted up a quick look at some of the new features coming with BlackBerry 10.3.1 from the SDK but since then, an unofficial developer build of 10.3.1 has leaked out and folks have been going through it and finding out what's new. For those of you not interested in loading up a leaked or developer OS, CrackBerry Forums member pttptppt decided to do up a video and show off some of the top features coming with BlackBerry 10.3.1. Give the video a look! BlackBerry 10 keeps getting better.
