You probably live in an area with decent cell tower coverage. If you have good reception, the signal attenuation won't be noticable.

But if you live in an area with poor reception, it is very noticable. For me, it always happened when I was in certain rooms of my house. I'd typically pick up my phone, walk out of the living room to not disturb the others, and then the connection would break up.

No other phone did that. The iPhone 4 had really crappy reception. People made fun of it, and it was absolutely justified.

I still loved the phone. The Retina Display was a breakthrough, and I still think it was the most beautiful phone ever made. But the reception was crappy.
