Hi! I have the same problem like nismo_developme. I had change my default security code and now I can't remember what it is. Now I bought another sim and every time I put this sim (2nd) in the phone it require the security code, (my 1st sim card work fine, not ask for the security code). My friend help me try to recover the code by using logomanager but it state "unavailable". If anyone of you know how to recover my security code please help me.

Regards,

VT
