iOS 4.1

Albeit a larger download for the combo but usually more efficient with several machines to update.

Very true, also more thorough is its a big update. Saying that I just let my updater do it all. Must admit even though its a an i5 680 dual core with HT its fast, I know Ghz are not the be all and end all but 3.6 with turbo boost to 3.8 is great geekbench score was 32 bit - 7021
64 bit - 7801 thats almost 400 ish points better than late 2009 i5 quad.
