Rusty may have given you an APK for ICS. Just to verify, are you using Cyanogenmod7 as your rom? If yes, you'll need to use Adobe Flash for GB.

Strange, I still see Adobe flash in the Play Store: https://play.google.com/store/apps/details?id=com.adobe.flashplayer
If you can't access that app, you may try to download the latest flash player appropriate for your device (scroll down, it's a pretty long list): http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html
