BlackBerry smartphone users who own RIM or third-party holsters/cases/pockets/etc. with compatible sleeper magnets can set their smartphones to answer or end calls when they're removed from or inserted into a holster. This feature can help save time and make it easier to handle calls while using a BlackBerry along with a compatible holster.

To modify call-end/call-answer holster-settings, tap the green Send Call button, and on the following screen, hit your BlackBerry Menu key--directly to the left of your trackball/trackpad--then pick Options. Next, open up the In-call Settings menu, and you'll see a section titled "Answer or end calls automatically".

In this section, simply set both the Auto End Calls and Auto Answer Calls options to one of the following choices, depending on your desired actions: Never, Into/Out of Holster, Slide Open/Close or Both.

Finally, tap the BlackBerry Menu key once again, choose Save to save your settings, and you're good to go.
