More importantly, I couldn't care less whose problem it is. I paid $70/mo to T-Mobile for three lines on a family plan, in addition to three free (admittedly crappy) phones, and had a stellar reception everywhere. Now I pay $80/mo to AT&T/Apple for a single line, in addition to $250 cost for the phone, and I can't make a single call without problems in 90% of the places I go to. The important message is "shut up, stop pointing fingers, and fix it", not a guessing game about whose problem it is. It will only become interesting to me from a purely intellectual, technical perspective when they fix the problem. For now, I couldn't care less who's at fault.
