The Dopod D600 is a basic PDA phone with a TI Omap 850 processor running at 200MHz, 128MB ROM/64MB RAM, 2.8" screen with 65k displayable colors, Bluetooth 2.0, and supports SD/MMC memory cards. It does not have Wi-Fi according to the specifications page, but this should decrease its market price considerably.
Looking at the specs, it is unclear how this would fit in with Dopod’s current offerings as the D600 offers less than the 818Pro on paper. Perhaps the D600 will only be marketed in Mainland China?
