Hi. I have a used 2G touch I just got off ebay. Seems to be working well. I do have a question about home button though. What is the proper touch on button to bring back home screen ? Touch home button quickly, and release ? Hold home button a few seconds, and release ? etc ? I feel like it is not always responding right away, but not sure if I'm touching home button properly. Could someone explain the proper touch of the home button to activate it ? Other question. When I bought touch on ebay it was advertised as having 3.1.something. It looks like they updated to 4.0 right before they shipped it to me. I actually did not want to use 4.0 on this 2G. Is their a fairly simple way to downgrade back to 3.1.2 or something ? My plan originally was to use 3.1 on this 2G. Then use 4.0 when a go for a new generation after it is released. Could anyone advise on downgrading to 3.1 please ?
