Paul Stamatiou has publsihed his review of the new Apple iPhone 3G. 'Hardware-wise, there are only a handful of real upgrades. Obviously, faster 3G connectivity ranks high on this list if you live in a city with good coverage. 3G reception in Atlanta has been great for me, but in Houston and Austin it is definitely spotty. In regards to the 3G vs EDGE argument, 3G is noticeably faster. I remember loading the New York Times homepage on my first generation iPhone over EDGE in 73 seconds. With 3G, that load time went down to 17 seconds (with 1 reception bar no less).
GPS is a very nice addition, especially with the prevalence of location-aware applications like Vicinity, Yelp, UrbanSpoon and many others. However, the built-in Maps application doesn’t have the ability to use it as a turn by turn navigation tool. You can use your current location as a starting point but it does not use it after you begin (just displays it). Also, don’t plan on using the GPS on any camping trips - the Maps application depends on an Internet connection to download the actual map tiles so if you don’t have any reception, the GPS is useless.'
