I've had the fake phone vibration thing, I just assumed it was a muscle twitch. Weird to think it's actually a mental rewiring!

I disagree with the fake phone vibrating being strictly mental re-wiring, or an itch from somewhere else being misinterpreted (by mental re-wiring). I get the fake vibrating ring all the time, whether or not I have my phone in my pocket, but it always feels like it comes from the same area where my phone usually is.

Being an engineer, I have always thought that the high intensity electro-magnetic field generated during a phone's ring has somehow damaged the nerves/muscles in the area closest to the phone. And since electrical impulses control muscle movement and the nervous system, they are a little screwed up (damaged?). Or they get stuck on repeat.

You see, I don't get too many calls, I don't answer my phone every time, I could care less if it rings or not, so why would my brain be re-wired to desire my phone to ring, creating phantom rings? It seems to usually happen when those muscles are in use (not just sitting down).

Wait, are they talking about multi-tasking (which nobody is good at) or task-switching (which is what most people do instead of multitasking, but call it multi-tasking).

Yeah I think his interpretation was a bit off, the study didn't test multitasking ability. Here it is :

The first test measured the ability to filter out irreverent distractions. The second was task-switching. Chronic multitaskers did much worse at both.

My interpretation after reading it is that there's a finite amount of working memory in your brain. Heavy multitaskers tend to keep recent tasks in working memory, because they assume they might need to go back to the task in a moment or two. Where as normal people are better able to flush out the previous task from memory, preventing the risk of confusing the current task with a previous one.
