Try it out now, here's how...
To soft reset your BlackBerry, using your QWERTY keyboard (not touch-screen), press and hold the ALT + Right SHIFT + DELETE keys.
Wait a moment while it appears to do nothing and eventually you will notice the LED turn red. Your BlackBerry will now do a soft reset without you having to take out the battery and do a manual hard reset.
