Although the title may sound like something you'd see on April Fool's Day, check the date - I assure you this is no April Fool's joke. Several sites and users are reporting signal issues when the new iPhone 4 is held in the left hand - there are even videos to illustrate this. The problem seems to stem from the location of the antenna band. The antenna band wraps around the edge of the iPhone 4. The problem seems to occur at the intersection of the WiFi and 3G antenna bands, in the lower-left corner. A few days ago, Apple apparently stated that it was aware of an issue with the display of the signal bars, but that it was merely a problem with the way they were presented, rather than the actual signal or ability to make a call. However, according to many reports, blocking the antenna doesn't merely result in lower signals, but sometimes results in losing connection entirely, causing the iPhone 4 to have to search for networks. Using a case seems to help the issue somewhat.
This is certainly troublesome news not just for Apple, but for the thousands of people who waited in line this morning for its release. If you've picked up an iPhone 4 today, let us know your experience.
