I am about to venture into the realm of neologism. Running the Canadian Word of the Year list for a couple of years has taught me the dangers, but I’m doing it anyway.
iOS 5 has two new accessibility features: “The LED flash and custom vibration settings let you see and feel when someone’s calling.”
That means not only can you set a ringtone for each of your contacts, you can set a flashtone and a vibetone. (Apparently not a true flashtone, i.e., different strobe or illumination patterns for different callers.)
