Apple iPhone 3GS
This is not the next revolutionary phone from Apple as all of us expected. But of course there are lots of improvements like performance boost, the sharper camera with video, purportedly improved battery life etc etc.
So this phone is the one that you could probably wave in front your geeky friends more proudly.
It may feel like Iphone 3GS is just a simple upgrade to Iphone 3G. But the fact is there a bunch of advantages for this over Iphone 3G.Lets have a look at those advantages.
iPhone 3GS advantages over iPhone 3G:
- A faster 600MHz CPU and double the RAM at 256MB
- Noticeably faster performance
- Faster network speeds of HSDPA 7.2Mbps
- 3.2 megapixel auto focus camera with VGA@30fps video recording, touch focus with subject tracking, macro mode from as close as 10 cm
- Double the storage space – 3GS is selling in 16GB and 32GB versions
- Digital compass with automatic map orientation in Maps app
- Better audio quality (as recorded and analyzed in our office)
- Louder loudspeaker results (with performance gains primarily in music playback)
- Purportedly better battery life
- Oleophobic display coating supposed to make fingerprints easier to clean
- Voice Control, speaker independent. Can be use to call a phone number, play music by song/album/artist name, shuffle music
- Built-in support for Nike+ jogging system
- Text-to-speech feature called VoiceOver is included in the new Accessibility menu
- System-wide Screen Zoom is also included in the Accessibility men.
Now as we have discussed the advantages, lets see the disadvatages. 
Main disadvantages of iPhone 3GS (OS disadvantages not counted here):
- The new iPhone 3GS lacks the same novelty factor as its predecessors – the lack of design changes is a turn-down
- 3 megapixel camera with limited feature set hardly cuts it for a high-end device
- There’s still no flash or hardware shutter key for the camera
- Despite the upgrade, battery life is still generally poor (2-year old iPhone 2G are still doing way better)
- No stereo speakers.
