Walt Mossberg, Who is Probably the Nation's Best-Known Journalist Writing About Personal Technology, Tells What He's Learned About the Controversial iPhone4 After Using It in Real World Situations for Six Weeks All Things Digital

If consumers can rely on anyone to tell them about the latest personal digital gadget, it's probably well-known journalist Walt Mossberg of the Wall Street Journal.

Mossberg now gives his opinion of the controversial iPhone4 after using it rigorously in real-life situations for six weeks.

His verdict? "I still believe it is, overall, the best device in its class, for reasons including its ultra high-resolution screen; easy, integrated video calling; slick software; strong battery life; a remarkably thin body; and a world-beating selection of 225,000 third-party apps.

"As for reception, I am sticking with my initial conclusions. I have found that in areas with average or strong AT&T coverage and capacity, the iPhone performs better than its predecessor and about as well as other AT&T smartphones I’ve recently tested. It still drops too many calls for my taste on AT&T’s heavily stressed network, which has experienced a stunning 5,000% rise in data traffic since the iPhone’s introduction in 2007. That data traffic reduces the network’s ability to handle voice calls."
