It was only recently that automatic profile switching was possible for BlackBerrys. It is still not a native feature and you need a piece of 3rd party software to accomplish it (Albeit with some caveats). Our buddies over at ToySoft decided to open the doors to more of you by offering 50% off of their popular Profiler application for today only.
To pick up the discount just head to the store and put Profiler in your cart. Then click the checkout button and use the coupon code 5050 to get your discount.
From the description:
Automate profile switching with Profiler. Schedule profile switching during the day. Integrate with Calendar application for profile scheduling
Note: Profiler will not change the Profile if the Blackberry is in the Holster or locked. You will get a vibrate and/or sound to notify you to unholster or unlock the device. Profiler will then switch the profile.
