Hey, I have a quick question: Does iOS4 on the now old iPod touch 32GB and 64GB models support multi-tasking? Also, what features of iOS4 did the 32GB and 64GB models support which the 8GB model did not? I can't find the info now that Apple have updated their pages with the new generation. I'm thinking of getting one with the Mac I'm about to get with the educational offer. Thanks very much!
