Not a joke... Seriously!
I get pins and needles in the tips of my fingers when using the phone, worse particularly when surfing the net. Gets worse as I continue using and eventually disappears when I put phone down. Made me concerned enough to google the problem and see if their was a known issue with the phone. At first I thought I had carpal tunnel syndrome (I'm a doctor)- but noticed it's only when using phone (no matter how I hold it), and I had no problems with 3GS. I think this is a very real concern- can't even use my phone for long period without regular brakes as the pins and needles become unbearable!
