That's news to me, and a great pity, as they work brilliantly!
It may be that they've ramped down production (did they ever ramp it UP properly???) to make way for some X2 accessories. Unfortunately the X keyboard and sync station won't work with the X2. :(
I think this is the case as I had one on order with MobileFun for ages and the other day they said they would not be getting it ever! So I swapped it for a UK charger, as I only have a Euro one with a big adapter!
