EDIT: Just got off of the phone with Justin at Sound Devices. Yes, you can update the firmware without the hardware upgrade.

Haven't seen this discussed anywhere...
Can I update my SD 744t firmware version from 1.74 to 2.03 without the new hardware upgrade?
I'm assuming yes. I just wanted to be sure before I do the deed. Gonna tape the Karl Denson Trio tonight.

i've run 2 shows w/ 2.00 and 4 w/ 2.03 and everything worked fine.
i ran 1 at 2.03 and everything was SOLID
just got an 8BG ridata pro 150x CF card too 8)
Ran 2.03 tonight without the hardware upgrade. Channels 1 + 2 mic in, Channels 3 + 4 digital in. No problems.
