Tech Specs – iPhone 3GS

Height: 4.5 inches (115.5 mm) Width: 2.4 inches (62.1 mm) Depth: 0.48 inch (12.3 mm) Weight: 4.8 ounces (135 grams)

4 Location Awareness

Location Awareness

Assisted GPS Digital compass – on the new ones Wi-Fi Cellular – it can even make calls!

5 Power and battery

Power and battery

Built-in rechargeable lithium-ion battery Charging via USB to computer system or power adapter But no built-in wireless charging like the Palm Pre Wireless charging is cool

6 Storage and Display

Storage and Display

16GB and 32GB capacity Display 3.5-inch (diagonal) widescreen Multi-Touch display 480-by-320-pixel resolution at 163 ppi Fingerprint-resistant coating Support for display of multiple languages and characters simultaneously

7 Camera

Camera

Camera located on back of iPhone. Put one on the front eventually? 3 megapixels Autofocus Tap to focus – tap on a part of the image Video recording, VGA up to 30 fps with audio Photo and video geotagging Interesting image search possibilities Microsoft Photosynth iPhone and third-party application integration

8 Sensors

Sensors

Proximity sensor Deactivates the display and touchscreen when the device is brought near the face during a call. This is to save battery power and to prevent inadvertent inputs from the user's face and ears. Now if we can get a ‘don’t call the most recently dialed number when the phone is in my pants pocket’ sensor.

9 Sensors

Sensors

Ambient light sensor adjusts the display brightness which saves battery power

10 Sensors - Accelerometer

Sensors - Accelerometer

A 3-axis accelerometer senses the orientation of the phone and changes the screen accordingly allowing the user to switch between portrait and landscape mode. The 3.0 update will add landscape support for other applications, such as email, and introduce shaking the unit as a form of input. Accelerometer can also be used to control apps, notably games.

11 Speed is critical

Speed is critical

Motivated by User Interface considerations Performance is critical on mobile devices Competitive nature Once you get a reputation as ‘slow’, you are doomed Remember Sun Solaris User experience

12 For our Applications

For our Applications

Shutdown quickly 5 seconds from user closing to write all data to non-volatile storage Otherwise iPhone shuts the app down regardless Fast performance – incoming calls

iPhone OS 3.0 adds new features, and the new hardware (3GS) has new capabilities

14 iPhone OS 3.0

iPhone OS 3.0

In App Purchase – More $$! Sell extra content and services from your application using the Store Kit framework. This new framework helps you keep track of your product catalogs, processes the payment transaction with the iTunes Store and returns information about each purchase. Apple Push Notification service Alert your users of new information, even when your application isn't running. Send text notifications, trigger audible alerts, or add a numbered badge to your application icon. Accessories Applications can now communicate with your accessories either through the 30-pin dock connector or wirelessly using Bluetooth. Build an app that retrieves data from external sensors or even control accessories with a sophisticated, Multi-Touch interface.

Peer to Peer Connectivity Add multi-player capabilities to your games using the peer to peer network connectivity and in game voice communication features of Game Kit. This powerful new framework allows any application, not just games, to communicate between devices using Bluetooth-no pairing required. Maps You can now embed maps within your applications using the new Map Kit framework. Map Kit works with the Google Mobile Maps Service and features panning and zooming, custom annotations, current location and geocoding. iPod Library Access Access music, podcasts, or audio books in a user's iPod library directly from your application using the updated Media Player framework. You can play, repeat and shuffle songs or whole playlists, or create sequences of songs using custom searches

Open GL ES 2.0 Games and other graphics-intensive applications can now take advantage of OpenGL ES 2.0, the latest version of the standard for hardware-accelerated graphics designed for mobile devices. OpenGL ES 2.0 adds programmable shaders that give you more control over the look of your scenes, allowing you to create more complex renderings and spectacular visual effects. Accessibility Make your applications accessible to everyone—even those with impaired vision. New to iPhone OS 3.0, VoiceOver helps users navigate through your application by translating standard gestures and providing spoken descriptions you include. Using the updated developer tools, you can easily adapt your iPhone applications to work with VoiceOver.

Video Recording Embed a video recorder into your application using the new interface used in the Camera application. The new interface provides a switch to toggle between still photos and video mode, giving your users the flexibility to capture the moment the way they want. Once the video has been captured, users can choose the videos they want from the updated Media Picker. Compass Add heading information to your location-aware application. Core Location has been updated to allow your applications to track which direction the user is facing using iPhone 3GS's built-in digital compass. While incredibly useful for any navigation-based application, when combined with the accelerometer the compass can also be used to capture iPhone's true orientation.
