After the success of their Rotation Lock app free launch promotion S4BB is following up with their next app Flip Silent. We have seen apps like Flip Silent before which simply lets you silence your BlackBerry by physically turning your phone face down. When you flip it back it returns to your previous profile.
They did not state exactly when this free month is over but until then you can pick it up in the store and in App World. Because of the need for an accelerometer this only works with BlackBerry Torch, Storm, and Storm 2 devices.
