The iPhone 4 Guide!

iPhone 4: The Definitive Guide

We must admit that with all the news and updates today this post is almost totally copied from Gizmodo.

Hardware technical features

The brains
It has an Apple A4 chip inside, just like the iPad. Inside the A4 there are a few interconnected chips: A Cortex-A8 main processor unit—the main brains—paired with a PowerVR SGX 535—which handles the high definition graphics of the new iPhone. These are directly connected with each other and two low-power 128MB DDR SDRAM chips. Since all these components are in the same chip, they can process things faster while consuming less battery than before.

The A4 also consumes less power because its sub-components can be switched on and off when they are not needed, shaving watts whenever it’s possible.

Battery life
The battery is 16% bigger than the current one. Coupled with the A4 processor and new display, it results in a longer battery life: Apple claims 40% more talk time. Here are their figures:

• Talk over 3G: 7 hours.
• Browsing over 3G: 6 hours.
• Browsing over Wi-Fi: 10 hours.
• Video: 10 hours.
• Music: 40 hours.
• Stand-by: 300 hours.

The display
The 3.5-inch screen has a resolution of 960 × 640 pixels. Apple calls is the Retina Display, and it has four times as many pixels as the current iPhone 3GS’ display. The screen has 326 pixel per inch resolution, a higher definition than your typical magazine, a quality that shows in the screenshot.

Apple claims that this IPS-based display—the same technology as used in the iPad—also has 800-to-1 contrast ratio which is four times better than the 3GS, with a higher viewing angle.

The apps will take automatic advantage of the increased relative resolution, which mean they will be a lot sharper for text, 3D graphics, and vectorial art. However, developers will need to include higher resolution bitmap images to make the app look perfect.

The main camera
The new iPhone has a bigger sensor for the main camera, with bigger lenses. This one is capable of capturing high definition video at 720p 30 frames per second. The sensor maintains the same 5 megapixel count, but it increases the size of the sensor, so it has a higher ISO. That means that you would be able to take better photos and video in low light conditions.

The camera also has a LED-based flash, which works both for photographs and video.

The video conferencing camera
In the front, there’s a video conference camera, with standard VGA resolution. This camera will be used with third-party applications, as well as Apple’s own video conference solution.

The new iPhone 4 has a gyroscope built-in. This means that it can track movement with a very high precision, much higher than the built-in accelerometers in the previous iPhones. It’s 3-axis, so it’s capable of detecting pitch, roll, and yaw. Couple with the accelerometer, you have 6-axis motion sensing.

• Like the iPad 3G, the new iPhone uses the new micro-SIM standard.
• It has an additional microphone on the top used for noise cancelation.

Black glass and stainless steel rim. It fits with the rest of the Apple product line, from the hard edges to the Dieter-Ramish utilitarianism of the iMac and the iPad.

The size is smaller than the previous generation: 34% thinner than the iPhone 3GS. Although it is 3 grams heavier. According to Apple, it’s the thinnest smartphone ever. It has split buttons for volume, unlike the current iPhone 3GS, all made in stainless steel.

As for storage, it maxes out at 32GB, so those of you holding out for 64GB are out of luck.

The stainless steel rim
The stainless steel rim gives the structure to the iPhone, and acts as an antenna for the phone. In theory, this will greatly increase the reception.

Video calling
However, the biggest feature of the new iPhone 4 is probably video calling, thanks to its front camera. Apple calls it FaceTime, and it works iPhone 4 to iPhone 4 over Wi-Fi—at least for 2010. Apple claims that in the future it will be available over 3G.


The iPhone 4 can use both cameras for video calling, so you can broadcast what is in front of you to another iPhone 4

iPhone OS 4 becomes iOS 4.


One of the smaller updates of the WWDC 2010 has been the renaming of the operating software which is used on the iPhone, iPod and lately on the iPad, the software previously known as the iPhone OS, has been renamed and is now simply known as iOS4. Personally we think that as this OS has been introduced on more hardware, it just didn’t make sense to continue referring to it as an iPhone OS.

iOS 4 will be publicly released on June 21st. It will be a free upgrade for existing iPhone and iPod touch owners, though depending on the age of your device not all features many be available. This is the first time that a major OS update has been free for iPod touch owners.

iMovie for the iPhone!


During the Apple Keynote just moments ago, Apple introduced the “new” iPhone 4 which introduces recording in HD format, of course you need an App for editing these videos if you don’t happen to have your mac with you, this is where the new iMovie for the iPhone enters the frame.

What’s iMovie for iPhone about? “Record HD video and edit with beautiful transitions and titles, all on the device you carry with you every day,” says Ubillos.

When you open the app,  you are greeted with a list of all the project you have, and can just tap on a project to get into the editing environment. When you rotate the phone horizontally, clips can be viewed at the bottom of the screen. Furthermore, you can add photos, as well as transitions which according to the demonstration are entered with a scroll box and even titles.

Of course you can’t expect Final Cut Pro editing, but for the basic fast editing on the fly, this app should be more than enough.  You’re able to combine various clips, add music, photos, titles and transitions as well as basic effects.  The videos can then be exported in 360p, 540p and 720p.

Right now the app will cost $4.99 from the App Store.
