If you look at the stickied threads at the top of the page, you'll see a thread titled...going back to gingerbread... You want 2.3.6.

 

Unfortunately I recently reverted back to gingerbread v2.3.6 as I found some widgets didn't like the font sizing in ICS. I also didn't like the messaging app emoticons, the light grey font on white backgrounds, the data activity icon for 3G is smaller and hard to see as it's black on a black/blue signal strength indicator, etc. It's little things like that which make the phone more annoying to use, and even though it's a smartphone, it's still a PHONE and I need to use it like one most of the time. Perhaps I'll try ICS again when they update it and fix some of these little annoyances.
YMMV.
