click wheel unresponsive: can I replace with 4th gen wheel?
I have a dead nano 4th and an unresponsive click wheel on a 5th.
Resets doesn't work (as no clicks at all).
Q1) Do 4th and 5th have compatible click wheels? Can I try to replace?
Q2) Any 'tricks' I should try before attempting to replace? (heard about a 'credit card' trick?
