Hello MPGH Members, my names Aslan. And I have a huge problem on my head... When I bought my phone few days ago, it was working perfectly, but later someone told me I should do some Android Updates... And then I did what he told me to do. Ones it updated it re-stared automatically.. but then something popped up saying " Sim network unlock PIN" I dont know what I have to do, is there anyway I can Unblock my Samsung galaxy S II? Please help me, Id be so grateful!
