am having trouble syncing my ipad 1 to a newly purchased iMac. have no had previous trouble syncing to my Dell PC. yesterday I saw a message on iMAC that a new iTunes version 10.6.3 was out and by its description it looked like it was aimed at the kind of sync problem I was having. so I upgraded to it on the iMac easily enough. but sync still would not work. do I need to do a similar upgrade on the iPad 1? if so I have no idea how to do that; or even determine what version of iTunes I have now. when I opened the iTunes program on the iPad it promptly crashed so I had no way to dig further into it to learn more etc etc etc. appreciate anyone's guidance. thanks.
