I love this phone!
It's an awesome phone. The form factor is amazing! It's almost as thin as the RAZR but it looks 1000 times better! I love the auto opening feature with just a push of a button.
I purchased mine from a store called UCLA Wireless on the SW corner of Valley and San Gabriel Blvd. You can also try SL Wireless, across from Office Depot just west of Atlantic on Valley Blvd.
The phone does not come with Japanese support.
You can always download a software compatible to a series 60 phones.
