Any techies here wanna weigh in on the controversial issue of the iPhone 4 antenna issues? Anyone have an iPhone 4? 1) Can you replicate the "death grip"? 2) Are you dropping more/less/same number of calls as the 3G(S)? 3) Does the supposed antenna issue affect your quality time with the phone? 4) Do you consider yourself to be in an area with weak/bad signal?
