Damn OP, you really need to chill! Not all phones are the same, and not all get rooted right when they come out.
Yes, it sucks that we're dealing with a new chip, and it's gonna take time to crack, but that's the way it is. I assure you that we have some of the best Dev's working really hard to get this going.
You demanding to have root by Monday or you'll return the phone only makes you look like a fool! Hate to say it, but we're not going to see root for weeks, or even months for matter.
All I gotta say now is... walk your sorry ass back to T-Mobile, and exchange the phone for 2 tin cans, and a long ass string.
