That is what I've read here about the same phones from both carriers.
Of course that could change at any time Metro decides to send an update to your Metro branded phone changing that IF your phone gets carrier updates. [EDIT] Like they did on the LG Motion.
Of course, with say a Nexus device, you can politely tell them in which bodily orifice you'd like them to stick ALL those updates. We don need na stankin' joy killin' carrier updates.
[EDIT2] This actually speaks as well for the Spirit as it does the N4. Updates cost the carriers money to accomplish. They're most likely to do it when there's real user issues with the phone that really need fixing. With the Spirit, there hasn't really Been anything to fix. Therefore Metro would have to pay for the update Just to kill the native hotspot app which thankfully, they haven't seen the need to do (yet).
