We've reached the end of our week-long marathon of Father's Day sweepstakes, and we think you'll agree, we've saved the best for last. Our final sweepstakes is for a TomTom ONE 3rd Edition portable navigation system. Valued at $199, the ONE 3rd Edition is TomTom's entry-level model but features a large 3.5-inch touchscreen, preloaded maps and 1GB of internal memory (Father's Day tie not included).

The Internets are abuzz with the announcement of an all-new iPhone, and with features like 3G data connections, new applications and GPS navigation, we're excited too. If you've been making plans to produce your own navigation app for iPhone 2.0, however, you may not be all that thrilled. A closer look at the iPhone SDK agreement shows that creating software for "real-time route guidance" is forbidden. This may mean that the creative kids at Cupertino aren't going to let anyone compete with the the Google maps solution it's already settled on.
