I don't have a droid (yet), but my windows mobile HTC is unlocked and bootloader patched.
I update firmware on it every month or every other month.
for my windows mobile roms I got to XDA forums, they also have tons or android roms, modded roms can sometimes look really different from standard rom, with custom themes etc..
And as long as you get it from reliable source they are safe as well. I almost always get them from same author.
