In the US, 8320, 8820 has WiFi; 8800, 8820 and 8310 have built in GPS.
No models have the 256mb memory.
If you wait long enough in 2008, you will get a device with most of that, plus 1gb device memory, but it very likely won't be a 83xx or 88xx series device.
You're correct, all sprint and verizon BB are evdo which is 3g. They have gps, but no camera, until the curve. Wi-fi on the cdma curve is still a ? Unless the curve is going to be a world edition like the 8830 then it won't operate on gsm though. We'll get there one day as technology keeps improving!
