Hello,
If I remember correctly, my unit came with v1.06.??. (I don't have a copy of this one, and don't know if it was released separately) . Then there was 1.07.01 (OK), and 1.08.07 (many complaints), both of which you also didn't list. I would stick with 1.11.03 unless you can't get it to work for you, but if you can't get it to work, there is no reason I can think of to go back further than 1.10.01.
