There must be something going on about copyright claims from Apple. Uxcell is not the only HK seller that does not sell the Nano clones anymore.
I found the homepage from our well known Tronfy Co. (= tinydirectdeal)
www.tronfy.com
And guess what, they also have no Nano clones anymore. They replaced them by models based on the Nano clone, but with a different lay out of the round control button. They also made a Zune style mpX player.
