Although the news of iPhone-4 leaked but Apple stayed with their plan and announced the 4th generation of iPhone model. Just like earlier when new generation of iPhone were launched the selling of old one was stopped (like first generation stopped selling by launch of iPhone 3G, and same as iPhone 3G selling was stopped after the launch of iPhone 3GS which would be sold for $99 for 2 years contract).


Apple has launched the next generation of iPhone- iPhone 4 with awesome new features, and will start selling iPhone 4 from June 24 at $199 with a two year contract in U.S. iPhone 4 will be available in two different versions; 16GB version costing $199, and 32GB version costing $299. Fro iPhone 4, Apple has renamed their opertiing system iPhone OS 4.0 for iPad and iPhone/iPad Touch devices to iOS4. For all the devices iOS4 upgrade will be available from June 21.

  • This time Apple has used stainless steel rims for binding the body of iPhone 4.

  • The front and back panel will come coated with fingerprints resistance oleo-phobic coating

With all these features, you’ll be able to watch comfortably 720p HD movies on 960×640 pixel display with more accurate colors.

3. Processor:

To conserve power to add up to the battery life Apple has used the same A4 System-on-Chip processor on iPhone 4 as earlier used in Apple’s iPad.


4. Camera:

The camera in iPhone 4 has some awesome features:

  • Apple has added a 5 megapixel sensor with backside illuminated sensor and LED Flash.

  • “Face Time” works out of box and does not need any setup or installation.
  • The “Face time” has been built using some open standards like SIP (Session Initiation Protocol), H.264, AAC and so on.
  • In iPhone 4 Apple has introduced new iMovie for video editing (which will include options like scene trasitions,themes, editable titles etc)
  • The iMovie app will be available for $5, but after the launch of iOS4 on June 21.

  • The “Three-axis gyroscope” is attached with Accelerometer, which make iPhone 4 capable of 6-axis motion sensing.

This feature is similar to that used in Sony PlayStation 3’s game controller which has gyroscope motion sensing.


6. Battery life:

In previous generations of iPhone the major issue that concerned Apple was of battery life, but fortunately this issue has been resolved and the new generation iPhone 4 comes up with a larger battery. This large battery is lithium-ion rechargeable and offers:

  • up-to 7 hours talk time on 3G network
  • 14 hours of talk time on 2G network

  • 10 hours of video watch

The most amazing thing in it is that now users can browse mobile web for up-to 10 hours.

7. Bumpers:

As the outer rims of iPhone 4 will be working as antenna system, so for that reason no other outer casing can be used. So Apple has come out with its own set of cases for iPhone 4 know as “Bumpers”. Bumpers are made by molded plastic and rubber, which will keep the antenna system as well as glass panels safe. They will be available in different colors like White, Black, Green, Blue, Orange and Pink.

8. Other features:

  • Quadband HSDPA/HSUPA

Other features like Multitasking and folders utilities will come preloaded with iPhone 4, but other Apple devices users can get these features once the iOS4 update is available for everyone. In iPhone 4 the iTunes 9.2 will be needed, so hopefully this iTunes software upgrade will be available soon.
