n900 has left me very frustrated with its phone function. and thats exactly what the phone feature is - another function. it usually has high priority over all other runnins apps so you dont miss a call but this hasnt always worked. recently my screen has started to go all grey when a call comes - regardless of what im doin. or the screen doesnt light up so i guess where the answer button is. although a fun game its not great when you miss urgent calls. yes i know - have i tweaked my phone? but of course. thats the reason n900 exists. i still love it to bits.
