I found a simple solution that worked for me, maybe it helps someone:
1. I reset my phone to factory settings, let my google acc. sync apps etc.
2. Installed and ran Framaroot (root setting Gandalf).
3. Normal reset phone.
4. Installed and ran App 2 SD, it allowed me to move most installed apps like games to my SD card normally, no other changes necessary.
* Note: When entering android app info, "Move to SD" is still greyed out, but moving apps works when moving from App 2 SD.
