Hey guys, before I install 0.5 I had the exact same problem. After using for a while, I am unable to install app when location set to External. But when choosing Internal, I can but I can't move app to SD. Anyway, I installed 0.5 and it solved all the problem. I was able to install Angry Bird and such which I couldn't do before. Now it starts to act up that way again. I have to go back and forth switching internal and external every time when I install app. Also some of the app were not able to install. I don't know if is it because of my sd card has some issue or something. Do you know how to fix this? Any body else experiencing the same problem?
