Hi. I just got a Mobilepro 900C - unfortunately, as you point out on your website, it has bootloader 4.5.1-6.
I have downloaded the zip file that will "update" it to ver 4.10
The question I have is, can I use a USB flash drive instead of a CF card? Would it work? I'm really hoping that you'll say yes cuz I'd really like to flash the rom today instead of waiting a week to get a CF card from ebay. I would use the CF card from my jornada 720 but it only has 16mb
