In the midst of losing the memory card on my wife's Slide 3G (she still is memory card-less), she installed and began playing Angry Birds. Its really chopping, especially on the point of bird/object impact. Is this a product of not having an SD card installed? She doesnt have any apps from the market installed and/or running except Angry Birds and Facebook. Memory issue? Or is this just how the game plays on the Slide 3G? Any help would appreciated. Thanks in advance.
