Or settings/about phone/status
Also check MAC address is still there!!
There is a backup option in Nitrality, free from Market.....
And, in the link I posted, there is a link to app on XDA, to backup/restore the /efs folder!!!
Are you using Root Explorer or ES to check the folder???

Currently all the things are working fine. But I came across the EFS related article after I flashed a different region Rom. So I was little bit wondering that Have I done a big mistake ?? thats why i posted here.
all the basband related things are fine including SIM, Wifi, etc. IMEI is also there.
in ES i wasn't enabling Root option that's why I was seeing the blank EFS folder. Now I have copied this folder manually to my PC.
I also tried to backup through Nitrally, it says backup completed, but i am unable to find the backup efs files.
I also tried Win32 (.net) application but due to unavailability of 4.0 framework , it couldn't run.
I noticed one major thing by changing the different region Rom that my product code has been changed. I think it will not have any effect on phone performance/function.
Actually I am in search of best Baseband (Asia) so that the Radio power consumption can be minimized. So I want to try all Asian Roms to check the power consumption in Radio.
Any further suggestions will be welcome.
