With the snap on cases, can you still slide out your keyboard. Im curious if the cases snap into each other, thus making it impossible to open the keyboard. Or snap onto each side of the phone, (top and bottom) and allow for the keyboard to slide out. I would assume the sprint cases allow the keyboard to slideout. I guess Im just curious about the sprint cases and any aftermarket cases people have picked up so far and your ability to use the slide out keyboard.
