Not your standard top five. CNet TV gives a brief rundown of the top five flaws they see in the soon-to-be released iPhone. These include, the lack of 3G networking technology, its small capacity (only 4-8 GB), and a non-removable battery.
They also gripe about the huge sticker price and the two-year contract it locks you into (without the benefit of a discount on your phone.)
So if you need a few more reasons to hate on the iPhone, check out CNet's video.
