Thanks to Riotr at XDADevelopers Adobe Flash Player 11.0- for ARMv6 - xda-developers
we now have a version of Flash that will work with our phone. I installed Adobe_FlashPlayer_188.8.131.52.apk on my Android 2.3.3 V20b rooted and it seems to be running fine.
This installs Flash Player Version: 10.3.185.360 which can be verified at Find version
and you can test it out with Flash Android Games, Free at Android Flash Games | Flash Android
I think it is worth a try and I hope you all enjoy Flash on our LG Shine Plus.
