Hey people Wondering if you can tell me why my touch 2g is slow to react. it seems to be really slow when scrolling through my podcasts. but not when looking through the regular music ? also some of the apps are slow too. seems like a RAM problem. Do some apps use up memory when not in use ? I don't have notifications on for much, just facebook .I switched it off and it didn't seem to help. I am running os 3.1.3 ? should i upgrade ??? please help !
