people says 21e still have the GCs.. ?
and best guide to flash? i have p925g (rogers)
I didn't hear of such thing. Maybe those people didn't flash the 21e baseband with the ROM.
The best way to flash a completely new ROM is the KDZ method. Here is the guide: http://xdaforums.com/showthread.php?p=18082599
As I already said, flash the 21E firmware. It fixes that problem.
