I got my X and the Verizon swivel holster and I must say that it is subpar.
It is hard to get the phone into and out of the holster with one hand (maybe only for right handed folks) because of the holster design.
The design of the holster also pushes on the buttons of the X when you put it into the holster. This turns the screen on because it pushed the home button and then it also does a voice search because there seems to be a bug where even if the phone is locked, the search button still works.
The swivel part on the belt clip of the holster also makes a loud clicking noise on each angle when you rotate it. very annoying.
anyone know of another swivel holster on the market for the X? I know seidio has one in the works, but it isn't out yet. only concern i have with the seidio one is that it looks like the spring clip is right in the middle of the phone, which makes it easier to take out of the holster with one hand, but that is also where the power button is. i wonder if it will get in the way?
