Keep or Lose MF9?

HI all,

I'm looking to flash my phone with a newer ROM. I'm currently on one I installed quite a while ago. I'm now a bit confused on which ROMs I can and can't use.

My phone is MF9 according to what I've been able to locate in the about settings and phone info programs. I keep seeing stuff about OD2, but I'm not really sure what that means for me. Also, isn't there something about updating and it doing something to the boot loader?

Do I need to update to OD2 to use newer ROMs?
Will it lock my boot loader and what will that do to my ability to change ROMs later?

Lastly, and I know it's a matter of personal preference, what ROM would you recommend? I'm just looking for something stable. Though good battery life and fast would be nice too.


Thanks,
-Jeff

Why does Google Maps lose calibration so often?

I'm not sure what it is, but for the last few years, all the Samsung phones I've had have always lost calibration in Google maps after every few uses. That's disgustingly annoying. Does anyone know why this happens and how to fix it permanently? Please don't suggest installing another calibration tool to fix this issue. I'm looking for a real solution.
