Can "Multi-Touch" technology of iPhone identify 5 or 10 touches at the same time? Let say you use your 5 fingers to touch &amp; open 5 apps in iPhone at the same time. If that is the case, then "can all 5 apps be opened at the same time?"
Yes, iOS multitouch will track 11 independent touch positions in the current SDK (iOS 7).

However, the springboard app won't launch but one app at a time, so the answer is no to having more than one app run due to precise multitouch tapping the home screen.
