So, if you want to go to 3.0, by all means... go wild, have fun with it.

Waiting until wednesday isn't all the sudden going to get your newly locked iPhone 2G re-unlocked with nothing happening on your end.

As I view that having a phone that will work on your carrier is most important, I would say to go ahead and do the DFU mode downgrade, get your phone re-unlocked and then do an upgrade to the 3.0GM as has already been outlined several times on these forums as being a safe upgrade path.
