What are the exact steps you have done to flash PP 1.4 NBB? Perhaps you have to repeat the flash procedure... Some time a rom get me mad at the first flash, then I only re-wipe all twice then reflash and -abracadabra- all runs fine!

The usual: wipe data, cache, dalvik, batt stats, create partition ext 512mb sw 0mb, but the weirdest thing of all is that the issue is only with one carrier, i tested it with another sim card (carrier Digitel-Venezuela 2g/3g both 900mhz) and it worked, so the problem seems to be 2g-850mhz/3g-1900mhz band :S before this rom i used n2 cyanogenmod and everything ok, and right now im using oxygen 2.3.2
