I was running a version of the sdk called 2.2.19a? or something like that, and there seems to be a marginally newer version on the devcenter site called 2.2.19 (drop the a). In short im trying to work out: 1) which version of the sdk to be using for 2.2.1 os 2) should I install the beta os for the ipod touch (my dev device) 3) should I install the iTunes beta? My app is simple, just calling images, with buttons to navigate between them. I dont forsee anything to make it 3.0 incompatible. Suggestions? I kind of need to work this out quick, im leaving for vacation tomorrow with no net access for a week, Im withdrawing already!
