Well, as I said before, ajack's file IS a flash plug in, although a highly unstable one, even for non 10.1 flash stuff.
Basically if you try to interact with flash content it crashes microB. Of course that's beating the purpose, because you can't maximize videos on youtube, or hit play/pause, or play flash games, or navigate streetview, but it does load them up.

On a side note, this might be a beta build, because the version it reports (10.1.105.6) is higher than any of the latest versions adobe has listed on it's about flash site:
10.1.102.64 For Windows
10.1.102.64 For Macintosh - OS X
10.1.102.65 For Linux
10.1.103.19 For Chrome on all platforms
10.1.102.64 For Solaris

Can somebody else try it just to rule out if my phone is the problem or the plugin?
