Flash for Android is usually updated to fix some bugs or patch some security holes. In fact, that's exactly what we are expecting on November 9th- with a fix to the exploit found late last month. However, that's not all that updates are there for, they can also be used to update the app for compatibility for future OS updates, Gingerbread (2.3) anyone?
As discovered by DroidLife the Adobe Flash Player 10.1 update page reads as follows:
ATTENTION: Please install the upcoming 11/9 update (ver. 10.1.105.x) to ensure that Flash Player loads properly with future OS updates.
Could this be a hit that we will be seeing Gingerbread soon? Rumor is that the SDK may hit November 11th and this is yet another sign that it's close!
