Invisible Shield for Apple iPhone 4!“I’ve been testing the iPhone 4 for more than a week. In both hardware and software, it is a major leap over its already-excellent predecessor, the iPhone 3GS,” Walter S. Mossberg reports for The Wall Street Journal.

“It has some downsides and limitations—most important, the overwhelmed AT&T network in the U.S., which, in my tests, the new phone handled sometimes better and, unfortunately, sometimes worse than its predecessor. But, overall, Apple has delivered a big, well-designed update that, in my view, keeps it in the lead in the smartphone wars,” Mossberg reports.

“The most important downside of the iPhone 4 is that, in the U.S., it’s shackled to AT&T, which not only still operates a network that has trouble connecting and maintaining calls in many cities, but now has abandoned unlimited, flat-rate data plans,” Mossberg reports. “Apple needs a second network.”

Mossberg continues, “However, on at least six occasions during my tests, the new iPhone was either reporting ‘no service’ or searching for a network while the old one, held in my other hand, was showing at least a couple of bars. Neither Apple nor AT&T could explain this. The iPhone 4 quickly recovered in these situations, showing service after a few seconds, but it was still troubling.”

“Just as with its predecessors, I can’t recommend this new iPhone for voice calling for people who experience poor AT&T reception, unless they are willing to carry a second phone on a network that works better for them,” Mossberg reports. “For everyone else, however, I’d say that Apple has built a beautiful smartphone that works well, adds impressive new features and is still, overall, the best device in its class.”

MacDailyNews Take: The AT&T millstone around Apple’s neck pollutes what should be a wonderful review. Read it and weep, Mr. Jobs. Then wise up – unless you continue to want your beautiful products to be obscured and marred by inept, greedy third-parties whose exclusive deals outlived their usefulness at least a year ago.
