Hey so my nds phat's left bumper is acting kind of odd. When pressed, it may respond, it may not. If I jiggle the button around a little, it will pick up on it, but the ds will think I'm pressing it multiple times... if that makes any sense to anyone. I ordered a triwing screwdriver from dealextreme and popped it open only to find nothing visibly wrong. Put it back together and its still not responding correctly. That would tell me I need a replacement tactile switch; am I right? Are there replacements available for purchase especially for nds? What does this sound like to you?
