from too much abuse? if you can't claim warranty for whatever reason, just check out the youtube video and buy the parts from your local Nokia distributor.
that's true but if you use the keyboard to type text, i would imagine the more common characters in english (or whatever language you are using) will be more open to abuse than from gaming??
I presume warranty should cover keyboard wear and tear....as that what it is there for....but if you are comfortable taking apart your phone an replacing the keyboard then go ahead! But I would send it off an let them deal with it, can live without it for a few days dont mind as long as ive still got something else to use in mean time
A lot of people (including me) were worried about this when I first launched it for the Droid but I haven't heard of any damage and it’s been 4 months. You can order the rubber buttons if you wish.
