The BlackBerry Dev Alpha was first given out back at BlackBerry 10 Jam in Orlando, Florida in May. Since then we have not seen much in the way of an update to the device as of yet. According to a twitter conversation between @funcoder and @BlackBerryDev that all should be changing very soon.
As you can see from the tweet below the update for the Dev Alpha is now in final testing and release cycles! So we suggest you get your Dev Alpha device charged up and ready for an update!
