First of all here is the pics of iPhones new and old: The iPhone 3G positioned next to the original iPhone. Even though the 3G iPhone looks smaller, it’s a hair thicker.

The Apple iPhone 3G is here, and it promises to be an improvement over the original iPhone. But how much of an improvement is it really? We take a look at the new iPhone 3G from all angles.

The iPhone 3G has almost the same look as the old iPhone, yet it doesn’t. It has the same glass display and Home button, but the sides are smoother and it’s a tad thicker. Though the iPhone 2.0 firmware update brings this functionality to old iPhones too, one of the most notable aspects of the new iPhone 3G is the App Store feature that lets you buy and download applications directly to your phone.The iPhone 3G has slightly more tapered edges, but that’s an illusion that hides the fact that it’s ever so slightly thicker (0.02 inch thicker to be exact). The iPhone 3G comes with a plastic back instead of the metal exterior of the original. The 16GB comes in black or white, while 8GB iPhones will only be in black. The iPhone 3G has the same ol’ 2-megapixel camera as the original. Finally, Apple decided on a flush 3.5mm headset jack for the iPhone 3G, which is a welcome change from the recessed headset jack on the original.

Just like the original, the iPhone 3G fits nicely in the palm of your hand. The iPhone 3G has the same icons and Home screen as the original. The iPhone 3G is certainly slim, but might not be big enough for a pocket. It’s small enough to not weigh down a purse or bag, though. One of the biggest features of the new iPhone 3G is that it has GPS. Here is a screenshot of Google Maps pinpointing our exact location. iPhone 3G comes with the new iPhone 2.0 software that supports Exchange e-mail, as well as access to the brand new MobileMe, which is Apple’s own solution for personal e-mail syncing. A very nice feature of the iPhone 2.0 firmware update that comes standard with the iPhone 3G is that it lets you purchase and download applications directly to the phone. You can get anything from games to productivity applications, in a range of prices.The iPhone 3G’s video player has the same interface as the original. Of course, one of the highlights of the iPhone is its full HTML Safari browser. The iPhone 3G comes with a full slew of language support, thanks to the iPhone 2.0 firmware.
