I'm trying to figure out what Javascript APIs I can use to achieve support for Mobile Safari back to iOS2. I haven't found a list anywhere that shows what version of Mobile Safari ships with each new version of iOS. I'm looking for a comprehensive list that goes all the way back to iOS2.

Thanks!

[Edit: Yes, I know and love feature detection. However, I have a set of targeted browsers I need to support, and I just need to verify that the fallbacks I provided cover my target audience and that I don't need to provide additional fallbacks that are cumbersome hacks).]

Since this is already the top hit on Google, we should start a list here. I'll make this answer a community wiki. By the way, I'm pulling these from the device's user agent string. Browser version is iOS version dependent, NOT device dependent. But when a phone doesn't support higher iOS versions it is listed:

3.2.2    - Mobile Safari 4.0.4
4.3.3    - Mobile Safari 5.02   - iPhone 3g
5.0      - Mobile Safari 5.1
5.1      - Mobile Safari 5.1
6.0      - Mobile Safari 6.0    - iPhone 3gs
7.1      - Mobile Safari 7.1    - iPhone 4
8.3      - Mobile Safari 8.0
9.2.1    - Mobile Safari 9.0    - iPhone 4s
10.3.4   - Mobile Safari 10.0   - iPhone 5
11.2.5   - Mobile Safari 11.0
12.1.4   - Mobile Safari 12.0
12.4.4   - Mobile Safari 12.1   - iPhone 5S, 6
13.0     - Mobile Safari 13.0
