To verify whether it's unlocked or not, just pop in a sim card from another carrier (for example, t-mobile), and reboot the phone. If the phone is not unlocked, it will prompt you for unlock code upon startup. 

Note:

• It does not require the phone to be rooted
• It works on 2.3.6 Android. I also tried 4.0.3 and it did not work.
• It works on Samsung Tool 12.1. Samsung tool 12.2, 12.3, 12.5 may have issues showing its unlocked but in fact it's not.
• If *#9090# code does not work then try the following: 1) power off the phone 2) connect microuart cable and power on the phone 3) now try *#9090# code again it must work 4) select USB diag and reboot the phone

How to remove BlackBerry IT Policy

Some blackberries have IT Policy set on it. Here's what you can do to remove it. I've tried the steps below and it worked for me.

Option #1:

• Download and install BlackBerry Desktop Manager from here
• Go to Start -> Run -> Type cmd
• Go to the apploader folder by typing the following in the cmd console.
  cd C:\Program Files\Common Files\Research In Motion\Apploader 
  or 
  cd C:\Program Files (x86)\Common Files\Research In Motion\Apploader  (64 bit windows) 
• Type loader.exe /resettofactory
• If your blackberry is password protected, you will be prompted for password. If you forget the password, you may simply try incorrectly for 10 times and the blackberry will then wipe itself out. 

It will work most of the time with option #1. But if it happens that it does not work, you may try the following. I have had some luck

with that as well.

Option #2:

• Download and install BlackBerry Desktop Manager from here
• Download the policy file and save it to C:\Program Files\Research In Motion\BlackBerry
• Go to Start -> Run -> Type regedit
• Navigate to HKEY_Current_Users\Software\Research In Motion\BlackBerry\PolicyManager. Right-Click the Policy Manager  and create a new string value named Path. Set its value to C:\Program Files\Research In Motion\BlackBerry\policy.bin
• Go to Options -> Security and choose Security Wipe on the device 
• Start BlackBerry Desktop Manager and connect the blackberry to PC

 

You can verify on the blackberry's Option -> Security menu that its IT Policy should be empty.
