Seems my G5 does all that already.
My wife actually gave it to me; I was quite skeptical. It is one of those things that doesn't seem like it would be worthwhile, but is surprising how often it gets used. It gives silent little vibrations when someone is texting or calling and you can check them out without getting your phone out. It also works good as a speaker phone when driving. It works better than the Bluetooth thing I used to have stuck on my visor.
Very thoughtful of your wife
