There were some rumors two days ago (we reported here), that the Brasil based company DesbloqueioBr.com.br unlocked the iPhone 3G by using a SIM proxy adapter. Today a confirmation comes from Vietnam. Two well known guys from the vietnamese forum GSM.com.vn going by the nicks TA_Mobile and Immb published some photographs showing a SIM proxy solution named X-SIM. However it requires an activated iPhone to unlock.
For those of you being capable of reading (and understanding) the original Vietnamese forum messages: this link is for you. All the others: enjoy the pictures here.
