monotouch development on 10.5.8

I can not (or do not know how to) upgrade my mac to 10.6.6

Currently I am running Mac Os X 10.5.8

What downloads do I need to be able to install MonoTouch for 10.5.8? Is it even possible?

According to Profess开发者_运维知识库ional Iphone programming with Monotouch book,

http://www.amazon.com/Professional-iPhone-Programming-MonoTouch-Programmer/dp/047063782X/ref=sr_1_2?ie=UTF8&s=books&qid=1301271660&sr=8-2

page I only need 10.5.7 version.

Is the book out dated?

Is there a way I can download older version of MonoTouch and be able to use it?

Please help.

Thanks..

My apologies, the MonoTouch documentation is out of date. Apple has refused to accept apps thru iTunes Connect with old versions, and they have dictated a 10.6 requirement, and as such we have dropped 10.5 support. I have updated the outdated page.

The Monotouch installation documentation claims that 10.5 is supported.
What is going wrong for you, and what leads you to believe that you need 10.6 instead?
