One of the traditional BlackBerry features that I truly enjoy is the earth magnet holster. There is something to be said for pulling your BlackBerry out of its holster and it automatically opening the latest email that arrived. Its one of those old school features that I was really hoping RIM would carry over to BlackBerry 10 but was missing in the Dev Alpha and PlayBook. RIM has just more or less confirmed that in their latest announcement of the BlackBerry 10 Beta SDK Arrival Boards. The Native Beta Roadmap details a new BPS Holster Service that is scheduled to arrive in the 3rd release of the Native Beta SDK.
This new API allows developers to determine if the device is in or out of the holster which is exactly how RIM does it now with BlackBerry 7. Its nice to see that RIM has not forgotten the small things. What other features do you want to see RIM carry over from current BlackBerrys to BlackBerry 10?
