I found an easy method to unlock the i9003.
To do this you will need an Hexadecimal editor and have root access to your phone.

Steps:

1. Make a full backup of the /efs folder
2. Get the nv_data.bin file located in /efs
3. Open it with an hexa editor (I used WinHex)
4. Go to line 181460 and modify from 01 00 00 00 00 to 00 00 00 00 00
5. Copy the modified nv_data.bin file into /efs
6. Set the appropiate owner user and group doing chown 1001.1001 nv_data.bin
7. Remove the nv_data.bin.md5 file
8. Reboot your phone
9. Enjoy!! :):):)

ADB commands:
# su
# cd /efs
# cp /sdcard/nv_data.bin /efs/nv_data.bin
# rm nv_data.bin.md5
# chown 1001.1001 nv_data.bin
# reboot

To check it you can do *#7465625# and verify that Network Lock is [OFF]

I hope it can be useful for you.

Can you upload or give to me your file nv_data.bin??

I try to generate to you a pin unlock code.

This is an experiment, unlock code may be not working.

We try to do, it is only a number PIN to insert.

Hey fyter, can u help me to unlock the region on i9003.
I bought an i9003 from Africa/Tanzania, but the problem is i cant use it in any other country.
I can use any network in Tanzania, but outside of Tanzania its not showing the network.
Also its not even asking any unlock code.
It seems that the region is locked.....
