I've used the c721 and it was a great phone. Took pictures on par with a low end standalone digital camera. The Ravine seems like it might be a little bit better in every regard except the camera is not as good. Just wondering if anyone has any feedback? My screen cracked on my c721, I suppose I could look at repairing it, but not sure where to start there. I initially replaced it with a kin twom as an upgrade, but am looking to go back to casio now.
