IPhone 3G features an amazing GPS System, which can show you exactly where you are, where you are going, as well as what kind of traffic you can expect along the way. The maps on the  iPhone 3G combines GPS, Wi-Fi and mobile tower location technology, using the Multi-Touch interface to create one of the best mobile map applications on the market.

If you ever find yourself in the situation of being lost, the iphone 3G could be your life saver. Your exact location can be found using GPS, or even by cross-referencing your location using wi-fi and mobile towers. You can even use the GPS system to track your route if you are out walking, and never worry about getting lost ever again.

The iphone 3G will enable you to see maps very similar to those on google. Know the address where you need to go, but don’t know how to find it? The maps on the iphone are clear and concise and let you toggle between different modes and satellite imagery. The maps will also show you live traffic information, showing you any traffic jams you may wish to avoid. The easy to use feature displays red, green and yellow areas to show you the best routes on the map.

In the vast, ever-expanding world of iPhone cases and films, it would be fair to say that 10% are merely decorative, 10% are solely protective, and the other 80% are designed to be some combination of the two. Until today, however, roughly zero cases have been designed to improve the iPhone’s core functionality, a number that increases to perhaps 3% if you count the few cases with integrated video stands. Griffin Technology’s ClearBoost ($35), therefore, is a major stand-out. Described by the company as an “antenna-boosting case,” which “improves reception as it protects your iPhone,” ClearBoost is the first iPhone case with an integrated, stub-like antenna at the top, as well as the first that measurably improves iPhone cell reception—under certain conditions.

Apple was today monitoring the latest mini-crisis to hit its much-hyped iPhone after some users began reporting that the touchscreen did not work. Threads on several Apple forums including the company’s own have been devoted to the problem, which causes parts of the device’s screen to go ‘dead’ and stop responding to the touch of a finger.

Typically the dead spot is a strip about half an inch wide that runs the width of the iPhone’s screen as it is held vertically, users experiencing the problem said.

In one case, the strip ran across the Unlock button, which meant that the user was unable to answer the phone when it rang.

“On the main screen, I can’t hit the button for clock, calculator, notes of settings,” ‘Gwas’, a user of the Apple-dedicated site Mac Rumors, wrote. “For text messages, I can’t hit the send button. On the phone keypad I can’t hit the 7, 8, or 9 keys.”

Another complainant wrote: “Now like 1/4 of the screen starting from the bottom doesn’t work.”
