upgrading x01ht SB extrom without locking the phone

[greengaijin]

Hello,
thanks a lot to all of you for the nice job you've been doing! I'm living in Japan and using a SB x01ht that was bought just after launching around october 2006. I'm still using the original version with bootloader 1.06, the only thing I installed was Asukal's english MUI. I haven't upgraded to the new extrom but now I need to have access to data communication. Can you tell me how can I do without simlocking my phone?
Tks and cheers,
Greengaijin

Hey Rudegar,
sorry but I'm a bit confused after reading Pof's FAQ regarding his unlocker for Hermes phones...

"Q: Will this work on Post April (white) SoftBank X01HT phones?
Yes if you have not let the SoftBank ExtROM install, otherwise your radio bootloader has been upgraded to 0182 and it is not possible to flash a radio or remove the SIMLock."

How come the ExtRom can lock the phone in the above situation?

Tks again,
Euler:confused:
