To me, having the phone able to perform basic notification functions (LED
blink, vibrate, make a sound) on certain events, even when the phone is on
standby, seems like a very desirable - not to say obvious - feature.

I was right on the verge of buying a FreeRunner when I read the message
above, but think I may hold off for now, as it looks like that sort of
functionality isn't something a firmware upgrade would enable. Is my
understanding correct? If so, am I also right in thinking that retrofitting
the hardware capability to do this would be *really* hard without serious
SMT-soldering/PCB-fabrication tools and a big investment of time?

Many thanks in advance for your help,

Sam
