No he's not!
Well kinda/sorta.
I am running the TW4 Eclipse but I am also running a separate complete TW 4 launcher.
You can run the TW4 Launcher on any Samsung phone without Eclipse (quite possibly on other manufacture's phones...never looked into it, though).
You can load the TW4 launcher without being rooted, but you won't be able to have it fully functional.
I gotta go though, I'll post more info and links on how to get it.
Root or not....it's still badass!!!
