We’ve got a really cool BlackBerry Deal Of The Day for you in the RIMarkable StoreBerryPopup, adds functionality to the BlackBerry that probably should be included in the OS.  Whenever a new email or SMS text message comes in BerryPopup, as the name implies, pops up a window allowing you to preview the message without having to switch from away from what you are currently doing.

BerryPopup is designed to pop-up in any application, giving you the opportunity to reply, forward, mark as read or delete messages on the spot –right from the preview window. No need switch to the messaging application.

BerryPopup normally costs $6.95 but its 50% off Deal of the Day Price is $3.47.  Check it out in the RIMarkable Store.
