where can i download unity iphone 2.6 or 2.7?

i have the new 3.0 version but my training videos are for unity iphone 2.6. the link in my old registration email for 2.6 no longer works and would like to learn how to use the old version before starting on the new 3.0. can someone provide me a link to the old version please.


Mac or pc

I may have my wires crossed and think the iPhone mac was a different version number to mac/win version. So I would probably be looking for 1.6 or 1.7 but this is a guess.
