Iphone 4G Specs | Iphone iOS 4 Specs

Hardware:

- iPhone 4G has 4.50 x 2.31 x 0.37 inches in terms of dimensions.
- It weighs 140 grams. Slightly heavier than iPhone 3GS.
- A front facing camera for video calling/chatting is there.
- A better back camera. The lense is noticeably larger than the iPhone 3G/3GS. Most probably iPhone 4 will have a 5MP camera which most /all of its rival Android phones have. The camera can also perform zooming. Only digital zooming, obviously.
- And yes, there is a flash light accompanying the camera! We might also see a flashlight application to use the flashlight separately as a torch. But that’s not much likely.
- SIM card slot is on the right side instead of top. Also it does no more support the standard SIM card. You will have to get a microSIM instead. Obviously, you can cut your current SIM to make it a microSIM.
- The screen has 960 x 640 confirmed resolution. But the screen size seems to be sightly smaller than iPhone 3GS.
- A noise cancellation mic on the top, next to the headphone jack.
- A standard 3.5mm stereo headphone jack.
- Bluetooth with stereo support but no file sharing.
- Unlike previous iPhone version, iPhone 4G has two separate buttons for + & – volume controls.
- Battery is a lot larger than iPhone 3GS, so you can expect extended battery life. Apple can even surprise us with the battery life as it did with the iPad.
- You’d be able to pair any bluetooth keyboard for text input.
