Thanks to MarketWatch for this tidbit: The issue we brought to your attention earlier, the iPhone screen becoming unresponsive, may have been known to Apple prior to launch. Apparently, Apple bought the multi touch technology from a bankrupt Finnish company, and that company discovered that after three to six months of use, the screens would fail. The technology that allows the iPhone its much praised multi touch abilities uses a chemical that detects the heat of a finger.

It is too early to say that this current problem is the exact same one the Finnish firm was aware of. It could be that Apple addressed that issue only to uncover a new one. Everyone said Apple was taking a giant risk with the iPhone, and that risk included the fundamentals of the technology itself. Multi touch is a fascinating new technology, but as with anything new, growing pains are to be expected. Hopefully, for the future of multi touch, and for everyone with an iPhone, the cause of the defects will be determined and fixed by Apple in short order.
