MMC interchange (N-Gage <-> Digital Camera)

Hi, I'd like to buy a digital camera which support SD and MMC cards!
Can I put on my MMC card from N-Gage to my Digital camera, shoot a photo, and put back on the MMC on cellular WITHOUT formatting the card? (Of course only small photos ... 640x480)
Digital camera and N-Gage filesystem are compatibles? Or N-Gage uses a personal fs structure?
I don't know if my question seem to be too silly, I have no idea if they are compatibles.

Thanks in advance for any response!

srry, cant give u a conclusive answer on dis 1.

Why dont u just try it?

If the Camera just puts the pictures on the Card and not in any sort of file structure then there shouldnt be a problem..
