This exact same thing happened to me when I flashed the Das BAMF Sense 3.0 rc4.9. I was getting a bunch of force closes on my apps (probably my fault with misuse of TB) and I could not move any apps to my sd card. I was getting the same message as you. I went on to their webpage to see what other were saying about this rom and it turns out that they have stopped development on this ROM so I flashed their "Uber BAMF" preview ROM and my phone is doing a ton better with this ROM. Over the past few days since flashing, my phone is settling in. I love this ROM! I'm now able to move my apps to the sd card. I did have the get the camera fix after flashing since it disabled the camera, but that's up a running again too. I do have to say, that with my extended battery, I'm at 50% when I go to bed at 11pm
...and I use HBO GO and iheartradio a lot through out the day. I'm thinking of going back to my standard battery. That sucker will probably last all day now
