Hey whats up guys/girls? So i just got a late 2007 macbook and i upgraded the OS to Lion. My question is, can i upgrade my macbook with any software so i can use the multi touch gesture?(using the 3-4 finger options). I've read that what i can do is to replace the keyboard/trackpad for a 2008 version of it because it'll have the chip/hardware include, swap out the ribbon that connects and it should work. So i was wondering if someone has ever tried this or is this another of doing this? Or am i just a fool with wishful thinking lol. Thanks for any input. Note: my macbook does support the two finger swipes but thats about it.
