When, therefore, we speak to you of God, we mean your own conception of God. - pg 47 of The Big Book of Alcoholics Anonymous; Fourth Edition

One's own conception of God could be any of those things I listed. Personally, I have spent nearly 4 years in an AA group. So rest assured, I have read the steps.

As to what is taught - God referring to Allah, The Flying Spaghetti Monster, Jesus, Mohammed, etc. - depends on the group/person/persons you've received your information from. There is no governing body for AA, and every group is completely self sustaining. Individual traditions, teachings, and cultures grow naturally in each group providing slight variance from group to group. However the core will always come back to God being whatever you choose God to be.
