Very good Article.
I have a Samsung Galaxy Note SGH-I717 which was locked to AT&T and running in ICS(4.0.3) . When I tried to unlock it through this method. After trying this, I searched in internet for ways to unlock my Galaxy Note and found that Using Unlock code is the best method to unlock which is also safe,easy and permanent unlock solution. So,I got unlock code from OnlineGSMUnlock.com and unlocked my Galaxy Note I717 . They also provide unlock solutions for almost all GSM phones.
