Apple iPhone 4 details at-a-glance

The phone:

The new iPhone is thin – really thin. It’s 9.3mm thin, which is 24% thinner than the existing 3GS. The new stainless steel casing is stronger, forming a band that is strong enough to support the internal hardware and act as the antenna.

There’s now a second microphone to improve the audio quality, while the iPhone 4 also has an improved camera, support for Wireless-N (2.4GHz only), a vastly improved screen and Apple’s A4 processor – first used on the iPad. The iPhone 4 also uses a Micro-SIM card.

The iPhone 4 has a five-megapixel autofocus camera with LED flash, using a ‘backside illuminated sensor’ for capture more light. Video offers 720p HD video at 30 frames per second, with one-click sharing and the option of using the new iMovie app (US $4.99 via App Store) to edit videos on the phone.

There is also a front-facing camera, for video calling. ‘FaceTime’ video calling is available via Wi-Fi only. Available from one iPhone 4 to another iPhone 4.

The iPhone 4 has probably one feature that takes the iPhone to the next level. The glass (for improved optical quality and scratch resistance) screen, measuring 3.5-inches, uses a new ‘Retina Display’ that has four times the pixel density. The Motorola Aura had a 330 pixel-per-inch (PPI) screen, but the iPhone 4G uses a 326ppi display – 960×640 pixels, or four times the resolution of the original iPhone models. It’s 78% of the number of pixels found on the iPad. IPS technology, also used on the iPad, offers an improved experience over OLED.


The iPhone 4 is a 3G phone with HSDPA support at 7.2Mbps (down) and HSUPA at 5.76Mbps up. There’s also support for Wi-Fi 802.11b, g & n.


Surprisingly, the iPhone 4 will only come with storage options up to 32GB.

Battery life:

The new iPhone 4 offers up to 300 hours battery standby, but Apple has also given some real-world figures for different types of usage:

3G talktime – 7 hours
3G browsing – 6 hours
Wi-Fi browsing – 10 hours
Video playback – 10 hours
Music playback – 40 hours


Apple has combined the gyroscope (three-axis), accelerometer and compass to give six-axis phone control for enhanced gaming. Other sensors include a proximity sensor and ambient light sensor.

Green credentials:

To keep eco-warriors happy, the iPhone 4 is Arsenic, BFR, Mercury and PVC-free. It’s also highly recyclable.

Operating system:

Apple is today renaming iPhone OS to ‘iOS’, meaning iPhone OS 4.0 – which will ship on the iPhone 4 from day one – is now called iOS 4. By the end of June, Apple claims there will be over 100 million iOS devices; including the iPhone, iPad and iPod touch.


Apple is claiming to be taking up marketshare in the eBook market and the new version if iBooks for iPhone will now allow notes to be added to pages and more interaction with content. In addition, any book purchased for the iPad or iPhone can be read on the other device at no extra charge.

Other things of note:

Apple also announced support for bing as a search engine, claiming Microsoft has done a very good job. It almost seemed like a suggestion that people might wish to switch from Google. Cynical or what?



On sale June 24th (US), with pre-ordering starting on June 15th.

Prices for USA are:

US$199 for iPhone 4 16GB

There is now a special upgrade offer for an AT&T subscribers that have a contract ending in 2010 – allowing users to get it up to six months early.

We’ll have to wait a bit for UK pricing it seems, as well as finding out if any UK network is going to offer such a generous upgrade deal.

Expect details soon though, as it ships in the US, France, Germany, UK and Japan at the same time. 18 countries will get it in July.
