I don't know what quite causes the delay, but every time I go to the Sony Building they tell me that upon ordering, you have to wait 3-4 months before they'll have the product ready for you. Perhaps they just aren't mass producing these?
Either way, I put in my order last week and they ought to be in in April. Otherwise, I don't know if you'll have much more luck with importers. Technically, I believe the Qualia stores are the only retailers of this phone.
