My end button is giving a double click instead of a single click. First the touch screen wasn't clickable. Meaning if your finger slightly touches the screen it's like you pushed down on it (Reboot fix that). Also did a wipe (erased .428) and installed .320 (same issue - with double click) - changed tap interval - swipe sens (same thing). Phone has never been droped - puzzling the crap out of me. Also I've been running .428 ever since it was released and it's been solid except for the SMS (which I can live with). Fellow blackberry user let's unit and figure this thing out - which has cause me sleepless nights
