I have the CECT P168 and is a good phone to me.
I found many things in a website dedicated to this model, including guides to make an audio adapter and settings for internet and MMS for various countries.

i have one, too. it's okay so far, but the camera and video recorder quality is really crappy! before you buy one (eg ebay - private auction) let the owner look if it has VGA, 1.3 or 2 mp! or you will -like me- be disappointed about this thing.. a problem is also the usb connection with vista, and the sms alphabet is really small. but the video player is great, the sound is really LOUD and the wallpaper you choose also appears in menues
