The upcoming upgrade to the iPhone firmware promises to bring a host of new features to Apple's smartphone and its sister device, the iPod touch. We also know that Apple will likely release an upgrade to the iPhone itself, with more memory and other enhancements this summer. But what about the iPhone touch's hardware? Does Apple plan to give it a boost as well? Well, if the Internet rumor mill is correct, the answer is yes. According to reports, Apple may add a built-in camera to the iPod touch. This jibes with Apple's supposed plans for a better camera with video-taking capabilities (at last) for the iPhone.
