Actually m somewhat confused .
M currently using CM NightlyFourE v4.2 (OLD BB).
So which zip so i select P500-v20G-baseband.7z or P500-v10E-baseband.7z for flashing the new baseband??

And also can i apply this method directly on on my currently running NightlyFourE v4.2 (OLD BB) rom ? or i need to flash the official 2.3 and then try dis method ?

Plz pzl let me kno!
