PocketPC.hk has details on what appears to be an upcoming E-TEN Pocket PC Phone Edition known as the G500. Unfortunately, access to the article requires registration, so we'll point you to this translated summary at
PocketPCItalia.com instead (if you're too lazy to register and/or if you can't read Chinese).
The G500 is very similar to the M600, which I
reviewed late last year. It includes a Samsung S3C2440A 400MHz processor, 64MB RAM, 128MB flash ROM, quad-band GSM/GPRS (Class B) support, a 2.8" QVGA (240 x 320) TFT-LCD, integrated GPS (SiRFstar III), a 1.3-megapixel camera with flash, Bluetooth 1.2 - Class 2 (with support for A2DP), and a miniSD slot. No Wi-Fi, it seems, but it does include GPS.
It's all a little sketchy at the moment, but it appears the G500 is geared towards an end of March release at an unknown price.
