Locked iPhone, pls help

[samircreep]

Ok, so I have a locked iphone 4g 32 GB that was brought from Japan and is updated to the latest ios 5.1. It is locked but for some reason I can do everything else like surf the net with wifi, download apps etc without a problem. I only can't use my sim.

Now I'm not an iphone expert. i went to eastern plaza and they said the unlock for this variety hasn't arrived yet.

My question to all of you iphone experts is: is there any hope for me? Can I unlock my phone at all anytime soon?

Any news/info would be greatly appreciated.

P.S: Also apparently i can't use a turbo sim with it yet, whatever that means
