I think you can.
I also think it's pretty easy, but you need to be really really careful.
I tried using the method xicotorro posted above, [http://www.youtube.com/watch?v=aZuiCsAtThw&feature=player_embedded|this] one.
Seems the gnex glass is connected the same way.
Tips:
* Heat the whole glass, this way the glass wont put much pressure on certain spots on the screen.
* Use a really really thin and preferably long plastic object. I tried using a guitar pick and it was too thick.
* Let the air bubbles do the work.
* Always keep in mind making sure there is extremly little pressure on the screen.
* Do not try to bend the glass up using the screen as leverage. Really. This might sound trivial, but thats how I broke the screen. (Maybe I'm just stupid)
* Underneath the screen, theres a tape-like thingy. Make sure not to affect this in anyway. (I don't know why, but it seems important)
* The edges are good insertion points for the plastic thingy.
Disclaimer:
I broke my screen. Apparantly the screen isnt very elastic. : )
Anyone in the Oslo, Norway area who happens to have a spare phone?
