Rebel into a 10D
I've been waiting to hear news of software hacks for the Digital Rebel ever since I read about the similarities between the rebel and the more expensive 10D model. The mechanics and firmware are the same, but the specs are software controlled, meaning that someone was eventually going to figure out how to remove the software controls.
Personally, if I can up the rapid fire shooting mode from the rebel's limit of 4 continuous photos to the 10D's limit of 9, I'll make flashing my firmware.
