Back on this Treo Pro thread:

http://forum.ppcgeeks.com/showthread.php?p=1712731

you said you could provide the stock ROM from your Verizon Treo Pro.
CMonex posted one of those somewhere, so I think I can find that if I need it, but what I'd like to know is how to back my stock ROM up before I go much further.

I'm trying to get a Sprint Treo Pro to work on Verizon and the outlook's pretty bleak.

Thanks in advance!
