Japanese iphone 4 questions

[-Blue-]

hi,

considering that the japanese cellphone system is diferente to that of europe and euro iphones don't work there, would a japanese iphone if unlocked work with a european SIM? in this case a spanish one

thanks

I've been using an unlocked Softbank (Japan) iPhone 3G in other countries, and it works just the same.

I have an iPhone 4 on BB 03.10.01 but since it can't be unlocked yet, I can't tell you for sure.

but have you been using it with the japanese SIM or with the corresponding county SIM?

idk if this was ur quetion, but i have a iphone that i got from japan and on the softbank carrier, and it works perfectly in the US.
I can even go on verison's network with the softbank sim card. So i guess the japanese iphones can go on any carriers network with the softbank sim card?(at&t, tmobile, etc.)
