ex-works unlocked 3GS now Blocked in UK
I recently acquired an ex-works unlocked 3GS and have been using it for some months, trouble free, with a pay as you go sim from an Austrian virtual network. I visited the UK in springtime and the cell connection was working fine. Now I am again in the UK and get "No Service". I bought another sim for 3UK, also pay as you go and this also gives "no service". I then got help from an iphone specialist dealer/repairer who tried several sims from different UK carriers. None of them worked. He told me the phone had been blocked in the UK and that he has seen many such cases.
Can anyone tell me if this blocking is by Apple or All of the tested carriers? Better still, is there a way to remove this block.
