I have a Orange SanDiego AZ210. It has a network lock.
This is the devices info:
Xolo_X900 (I used the 299 zip)
05.A5 (I didn't pass the OTA upgrade, so I rooted)
SUNRISE_SMB_REV30_V2_R3_1233.B (I don't know what is the relationship between it and network lock)

This phone is great! It's better if can make a phone call.
But I almost never seen someone to unlocked.
