The movement that iPhone came into market brought a technical revolution
in the cell phone market. People found some imperfections while loving
it. So based on the weakness of iPhone, Apple Inc. launched the second
generation of iPhone, iPhone 3G in 9th June, 2008 which had been improved
in many parts. So we will make a comparison of the two generations to see
what had been changed in iPhone 3G.

1. Outlines.
As we can see from the pictures that the colors of iPhone is part black
and part white. But iPhone 3G is totally black or totally white. The
covering of iPhone was metal while the 3G's was plastic so the 3G is a
little lighter than iPhone. And about the size of two cell phones, 3G is
a little bigger than iPhone which is hard to been found by eyes.

2. Main Body
Comparing with iPhone, iPhone 3G took lessons from the design of MacBook
Air, so the arc on the back of cell phone made the phone looks much more
beautiful. The other point was that the headphone connector that was a
big problem in the past Apple products was improved. The 3.5 mm headphone
jack was designed on the side of the cell phone and it makes every kind
of headphones possible to be applied.

3. Networks
The difference of networks was most obvious difference of the two cell
phones. iPhone did not support the 3G networks that made it a target to
be criticized by the medias. This time, iPhone 3G had stepped up to 3.5G
level and support WCDMA/HSDPA networks. According to Jobs' saying the
speed is much faster than Nokia N95.

4. Built-in functions
Another advantage of iPhone 3G was that GPS module was added which
supports the mobile navigation and location search. The camera was the
same as iPhone, but for the GPS, it could provide the geographic grid of
the pictures. The cell phone could record the latitude, longitude and
altitude of the shooting locations. And the picture element per inch
(ppi) of iPhone 3G increased to 163 ppi from 160 ppi of iPhone without
any improvement of the screen and distinguishability.

5. Battery
The battery of iPhone 3G was still designed as fixed as iPhone. The
standby time and speaking time of iPhone 3G had increased much by
comparing with iPhone. The speaking time in 2 G networks increased from 8
hours to 10 hours and the standby time increased from 250 hours to 300
hours. But the online time, music and video playing time did not changed
comparing from the past. Besides, there is a tool in the sales package of
iPhone 3G to help the customers take out the SIM card easily.

6. Software
The improvement of iPhone 3G in software was effective. It could support
many languages, Chinese, Japanese, Korean and other Asian languages. And
it support gesture recognition. The iPhone 2.0 firmware could support
AppStore software store that the developer all over the world could
discharge by free or sell iPhone software through the store.

7. Price
The last difference that the customers could experience themselves was
the price of the two cell phones. iPhone 3G was only 199 dollars when it
first come into the market. So it was cheaper than iPhone.

All these differences put together, we could find the difference of
iPhone and iPhone 3G clearly. But in all they are cell phones, though
they have differences, but they would not change very much. They are
Apple's cell phones.
