... The launch comes amid early reports of hardware issues, too.
According to The Unofficial Apple Weblog, several iPhone 4 owners are experiencing small yellowing areas at the bottom of the screen that are brown/yellow in color. This issue happened with the original Palm Pre and was caused by slight overheating, although there aren't any reports on what's causing it with the iPhone 4.
Engadget is also reporting that if you hold, or block the phone's left corner, the iPhone 4's antenna can't correctly connect to the network, and could drop calls. The left side is home to the device's GSM/UMTS antenna. The site said that using Apple's bumper accessory alleviated the problem.
