This isn't specific to a particular phone, but there isn't a generic "rooting questions" forum, and I've got the Hero so...
I'm a linux user, so the idea of rooting the phone is one of the many reasons I picked up this phone. However, I've been reading the forums and searching around, and have yet to find anything about rooting *from* linux. Ubuntu and Fedora find the Hero beautifully; I've had better response mounting this than some portable hds I own.
But has anyone successfully tried rooting any Android phone from a linux OS? I'd really rather not install Windows just to do this. I imagine Wine might help, but there's got to be a better way to access linux-to-linux than using Windows.
