FYI for those who didnt know (like me - thanks Paradoxsm)

The Sanyo 4920 and 2300 (non-camera) phones can recieve photo messages. They receieve and display the photo in exactly the same way as an 8100/8200/7400/5600 using lightsurf/wap. They can be saved to the phone for future viewing, set as contact photos or wallpaper.

I am not aware of any method to send or forward a photo using these handsets.
