www.rzr.online.fr, use Phoenix and flash it with cfw, maybe you played with your SIM card and got disconnected keyboard, but that wouldn't do anything to touch because touch is connected on different place, so, i doubt it's hardware.
you can find cfws on dailymobile forum
e7 is best symbian device nokia ever made (still didn't tested pureview) though.
//edit:
i am running moded Anna (my own cfw) named Maria Anna still didn't upgraded to belle :S
icemaker, you must be kidding, are you? e7 is like terminator for n900
