iPhone 4 Issues

The iPhone has been reported to have a signal loss defect caused by the design of the antenna. Consumer reports has indicated that when a finger is placed over a small gap on the lower left side of the phone a large drop in reception occurs.http://blogs.consumerreports.org/electronics/2010/07/apple-iphone-4-antenna-issue-iphone4-problems-dropped-calls-lab-test-confirmed-problem-issues-signal-strength-att-network-gsm.html They recommended that a temporary fix is to place a small strip of duct tape over the gap which will lessen the degree of signal loss. .http://blogs.consumerreports.org/electronics/2010/07/apple-iphone-4-antenna-issue-iphone4-problems-dropped-calls-lab-test-confirmed-problem-issues-signal-strength-att-network-gsm.html Apple is also providing free cases to owners that will also help improve the problem.http://www.macobserver.com/tmo/article/early_free_apple_bumper_case_orders_shipping/

Apple has announced that the white iPhone 4 will be delayed again. Quality control issues have added another delay in the ongoing saga of the white iPhone 4.http://www.eweek.com/c/a/Mobile-and-Wireless/White-iPhone-4-Delay-Echoes-Past-Apple-Issues-570538/

Reviews

"Overall, the iPhone 4 outclasses pretty much every smartphone on the market in terms of industrial design. It just comes off like a far more expensive device, like a Mobiado or Vertu -- but better designed."—Joshua Topolsky with engadget.com.http://www.engadget.com/2010/06/22/iphone-4-review/

"With the iPhone 4, Apple again shows that it is a powerful player in the smartphone wars. It won't be for everyone, the call quality and reception vary if you don't use a case, and AT&T's network remains a sticking point, but the handset's striking design, loaded feature set, and generally agreeable performance make it the best iPhone yet."'—Kent German for cnet Reviews.http://reviews.cnet.com/iphone-4-review

"As far as system performance, the iPhone 4 is very snappy. Apps load almost instantly. I have no complaints at all as far as that is concerned. I also have no real complaints about battery life."—Julie for The Gadgeteer http://the-gadgeteer.com/2010/08/09/apple-iphone-4-review/
