I cannot set-up my iPhone 5 as I am unable to install itunes 10.7 on my mac as i need Mac OS X version 10.6.8. I am currently using version 10.5.8. Is there a free update or do I HAVE to buy the new Mountain Lion software?

No, but you do at least have to buy Snow Leopard. Whether you can run it depends on what iMac you have:

Whilst Apple have withdrawn Snow Leopard from download, you can still get it from Apple by calling 1-800-MY-APPLE (if you are in the USA) and they will supply the SL DVD for $30. You can also purchase the code to use to download Lion from the same number.

If you are outside the US call your national Apple Helpline:

Klaus is spot on ....

You can only buy from apple tele sales

Here in the UK it will cost you £14 including shipping
