iPHONE 3G
FINAL FANTASY OR FINAL VERSION
“This is the final version. It’s got everything on it, including a little apple symbol, so there’s no way a better one will be in the shops by Thanksgiving.”
Steve Jobs on the iPhone 3G at WWDC

WHAT MAKES THE APPLE 3G iPHONE TICKS?
On the outside the iPhone 3G doesn’t look much different from its predecessor. But on the inside, Apple did make some signigicant upgrades. You get to have a new motherboard and the new GPS chip.
Basically the new motherboard feature support for 3.6 Mbps HSDPA, 2-megapixel camera and NAND memory. But the next-generation Apple iPhone 3 will see 7.2 Mbps HSDPA, HSUPA, NAND memory support and possibly an improved camera.
The GPS chip in the iPhone 3G is one of the best available in the market providing faster signal searches, improved tracking sensitivity and low average power consumption. You can quickly get a time-to-first-fix (TTFF) of your position because the GPS is combined with features like Assisted GPS (AGPS) and Long-term orbit (LTO) extended ephemeris assistance. Apple doesn’t stop here, it also make use of Wi-Fi networks when available for a smooth fix of your location.
You can expect to see many software optimising the GPS chip in the iPhone 3G. There is a very useful software “Loopt” which is basically a buddy list with GPS locations. So, you can see where your buddies are on a map. If Loopt links up nicely with the major online social networks, you can start adding all of your online buddies to your Loopt buddy list. The best part is that Loopt is platform independent, so it will also work on other phones too.
On the memory side, there is no further upgrade after their previous upgrade of 8GB or 16GB flash drives. Prior to the launch, I was expecting anything higher than 32 GB. The 8GB and 16GB small price difference today gives no reason to retain the 8GB. If you check out the market, many manufacturers are moving to higher capacity for their high end devices.
The new iPhone 3G has enough battery power to keep you going the whole day without running for a rechargen. You get up to 10 hours on 2G, 5 hours on 3G, 7 hours of video playback and 24 hours of audio playback.
