I don't know if it was this thread or another one, but somebody asked about the # key as a shortcut to change between silent and general profiles. At the time I was using an E71-1 and indeed, pressing and holding the # key switches profiles like on the N95.
I'm now using the E71-2 and can confirm that this shortcut no longer exists. Instead there is a really cool on-screen contact search that activates when you start typing letters in the home screen. I never saw that before! As cool as the silent profile shortcut was, I'd much rather have this nifty contact search.
Actually, I'd like to have both, but if I had to choose I'd take the quick search.
