Any Streak Upgrade/Downgrade "Gotchas"?

[Guest toyfreak]

I've been everywhere from stock AT&T 1.6 to Stephen's builds to untouched 2.2 and back with no problems getting where I need to go (albeit the process can be lengthy depending upon the upgrade/downgrade path). My simple question is this:

Can we back ourselves into any corners doing all of this or is the Streak an open book ROM-wise? My assumption is not being NAND-locked gives us free rein over the device.

The white streak is a dirty hooker that needs extra sweet talking B) :) :)

Seriously though, if you have a White one, for whatever reason, you can't up/downgrade via normal channels.
