Let's just hope that these problems that seem to be plaguing the iPhone 4 release are blown out of proportion and only affect a very small percentage of units... because at this point we've seen 2 pretty major design flaws. The newest one to hit the phone is a slight discoloration. In portrait mod it seems to be in the bottom right and is about the size of a pencil eraser... in landscape mode it can show up as a yellow line across the entire bottom of the screen. It is most apparent on white backgrounds, such as the settings page. Mashable has more info: Critical iPhone 4 Issues and Complaints Are Mounting Any users on the site experiencing this?
