So now that I made one little change and dyed my trackball - not so much a virgin anymore - if I changed the housing and keyboard would a different keyboard be more quiet when typing? I L-O-V-E my Curve, but just wondering if it would be less creaky.
My understanding is that you can turn the keyboard sound off. I looked at the manual at BB.com for your device and it looks like you can turn it off by doing the following: In Device Options > Click Screen/Keyboard > Set Key Tone to Off > then menu and save.
I would check that the key tone is off and try that before getting a new housing and/or keyboard. I saw someone on the board today that is uncomfortable with a new keyboard they just installed.
A friend of mine changed his keyboard 2 weeks ago and it was an OEM keyboard as far as I know, after it was changed I noticed no difference with typing - sound or otherwise. Good luck.
