You are complaining about performance using a hacked non official rom on your phone? Ok then. :/I'll give JB the benefit of the doubt because it's an alpha version (front-facing camera isn't working, ffs), but if the freezes are still there in the final stable ROMs, I'm done with Android. Google has got enough passes from me, freaking mobile phones shouldn't need multiple CPUs and gobs of RAM just to run smoothly. I don't care about apps, just make your own damn OS run decently!
