z1s back glass quick question (please read) topic

im wondering, i know the z1 and z1s are basically the same device with the z1s being the tmobile variant. can anyone confirm the back (shattered) glass is the same from the z1 to the z1s? i have searched high and low for the specific z1s back that says tmobile...cannot find anything but the stock z1 glass.

im fine with the z1 glass, actually id like to debrand the phone as much as possible but...i need to know it fits prior to ordering.

thanks in advance for the feedback.
