If you flash back to stock and relock, and have the same problems, then you MAY have a hardware problem. I wouldn't be so quick to blame your problems on a custom rom, since I haven't seen anyone else post about the same or similar problems you have. I would go to the advanced exchange website and swap out your phone.

I don't understand why there are people answering you by bashing on custom roms. This site was built on the fact that people are "customizing" their phones. And - since there aren't a whole bunch of people using MightyRom or JuicyRom reporting those issues, I think its more with the phone and not with the software.

So yes - exchange your phone. I think you have a hardware problem.
