Welcome to AF!!!
I dont think it will work but, a good guy to talk to is Robobob, a member here. Perhaps he will see this or you can p.m. him. He's from Japan.

Edit: I see you are offline atm but I p.m.'ed him for ya to take a look at your post.

 

Hello!
AFAIK, there shouldn't be any h/w barrier to using the phone in the US, it should only be software related. As its a CDMA phone it is registered to KDDI au, so I'm not sure how you would flash it to Sprint/Boost or whichever carrier. Perhaps flashing an RUU with all the .img might work. Sorry I can't be of more help

 

Thanks Robo,
You are now my Japanese contact/friend from across the ocean!
You'll probably hit ocnbrze first then me if you throw a rock at us seeing as tho ocn is in California I believe. lol

 

yep LA baby.

you i believe that if you just take the phone in to a sprint store, they should be able to activate the phone for you.

 

Radio frequencies for cell phones aren't the same from country to country. They try to overlap as best as they can but if some reason the bands don't overlap I don't think it'll work.


Cell phones are made to operate within that certain range.


Anyway I'm not sure, so let us know how it goe

 

Is Sprint in the 800Mhz range? If so I think it will be compatible, as that is what KDDI au operates in. If so I'm assuming that's why a lot of the overseas phones used by au mirror those of sprint (Evo4G/3D, Photon, E4GT..)

 

You can't switch out the sim as it's a cdma phone so it's built into the hardware.

 

Fadelore,
Dunno if you still checking up on this but I sent you a pm, if you decide to sell it before leaving. That is if you haven't left already!:screwy:
