A few days back on the 6210 Navigator I found out about the built-in FlipSilent. Now I've found out a shortcut to message reader.
A long press on the 'Show' softkey on the '1 new message' prompt opens up Message reader.Nice thing for the visually impaired.
Can't say the same happens for all FP2 devices as this (N85) has no built-in FlipSilent.
A similar find was 'Receiving via Bluetooth' notification by Vaibhav on the N85
May be there's some more treasure need to dig more.
