iPhone 4 vs iPhone 3GS

In comparison to the iPhone 4, the iPhone 3GS looks outdated, primitive and bloated. Here are some specification comparisons between the two:
Inside iPhone 4

The lithium-ion battery takes up most of the space inside the iPhone 4, and the official info pictures show that everything is magnificently placed and the iPhone is a masterpiece in technology architecture. Also, the switch from SIM to Micro-SIM allows for more room inside the iPhone 4.
iPhone OS 4 is now iOS4

The new iOS4 comes with 1500 features and developer APIs, and will be released on iPhone 3GS, iPhone 3G, and iPod Touch on June 21st, free of charge.
Apple decided to change the name of their anticipated OS from iPhone OS 4 to iOS4, which makes sense because “phone” is no longer needed since the OS will be on iPhone, iPod Touch and iPad. Very clever, Apple.
Bing isn’t the default search engine

Despite numerous rumors claiming that Bing would take over Google as the default search engine, Google still remains number one on iPhone 4. However, Bing is included as a default search engine option.
iBooks for iPhone

Apple realized the success of iBooks on the iPad and ported the same service to the iPhone 4 and iOS4. Now you can view PDF books on your iPhone 4 and if you bought an iBook on the iPad, you can use that same iBook on your iPhone for free!
Video chat on iPhone

State-of-the-art video chatting is now included on the iPhone 4 with HD clarity over Wi-Fi. The only limitation to FaceTime video chatting is both chatters must be using an iPhone 4 on a Wi-Fi network.
Apple plans to expand on FaceTime in the future and make it an industry standard. So far, it looks pretty sweet.
Bigger battery on iPhone 4

With the iPhone 4 battery taking up almost half of the hardware space, longer battery life is expected to follow. Here are some specifications and statistics for a fully-charged iPhone 4:
7 hours of 3G talk time
6 hours of 3G browsing
10 hours of wifi browsing
10 hours of videos
40 hours of music
300 hours in standby

The iPhone 4 brings high-tech mobile communication fantasies to life! Star Trek fans won’t have to pretend anymore…
