[2.0 hardware unlock]Came across this hardware unlock method
I searched for this link and nothing came back so sorry if it was already posted
Someone in Brazil has developed a SIM card hardware unlock that tricks the phone into thinking it's operating on the correct carrier:
"Our procedure consist in using one SIM adapter to simulate a fake IMSI test card. Instead of the AT&T IMSI like in the universals."
No info on availability of this SIM adaptor yet.
