Does anyone know how to unlock the Verizon Samsung Saga SCH-i770 to use on an overseas network (such as Japan) with a Sim card from that country? I've read some posts and some people say you need to enter the service code "000000". A Verizon tech actually also gave me this code. So I tried dialing **772 and then entering the zeros, but all it does is get you into "Service Mode" and show you your MEID. I also read that the latest Microsoft update AKU 1.5.1 does some sort of unlocking "MMS Over GPRS Supported", but I'm not if this is what I'm looking for?
