Checking Lock Status for (Xperia Models Only)
It is important to check if your Xperia has enough attempts to enter the code, otherwise even the correct unlock code will NOT WORK. There are no refunds if you purchase a code and your phone is hardlocked. Please check first before ordering!
If you have an Xperia X10 or X8 Model

press *#*#7378423#*#* and access the service menu > simlock
You will see a menu:
[X] Network 10 [ ] Network Subset 10
[ ] Service Provider 10
[ ] Corporate 10
[ ] Sim 0
If it shows [ ] rather than [x] for all the boxes above, it means your phone is fully unlocked.
If it shows [X] Network 0, it means your phone is hardlocked, 0 attempts to enter the code. You can only unlock your phone via Xperia Unlock Software in this case.
The best way to tell if your phone is unlocked, is just input a non accepted simcard, and see if you can make a call with it.
