The new 5 megapixel camera features 5x digital zoom and adds 720p HD video capture at 30 frames per second. Apple also will be releasing an iPhone version of its iMovie video editing software that will make it possible for users to record and edit video. It will be available for $5.
Three antennas are integrated into the design; one for UMTS and GSM, one for Bluetooth and one for WiFi and GPS. The phone supports 802.11n wireless networking and quad-band HSPDPA/HSUPA networking which theoretically can support 7.2Mb/s download and 5.8Mb/s upload. Jobs joked that these figures are theoretical because carriers don't support them just yet.
Driving the new iPhone is the Apple-designed A4 chip which puts an emphasis on power management and space saving. Combined with the new battery, Apple says this will boost talk time to 7 hours. The battery can provide 300 hours standby time, 10 hours WiFi web browsing, 40 hours of music, 10 hours of video or 6 hours 3G web browsing.
The device keeps a 3.5-inch display but pushes the resolution to 960x640, amounting to 4 times more pixels than the previous model. The pixel-per-inch count of 326 is a big improvement over the previous 163 pixels-per-inch achieved with iPhone 3GS, and made possible with the new "Retina Display" technology.
Showing more confidence in the platform for gaming, iPhone 4 adds a three-axis gyroscope. In addition to the accelerometer, it provides the iPhone with six-axis motion sensing. Developers can also utilize new CoreMotion API for position information.
For Jobs' infamous "One More Thing" moment, he demonstrated video chatting capabilities using either camera on the device in landscape or portrait mode. However, the video chatting feature, called FaceTime, is only supported between iPhone 4 handsets over WiFi for now at least for the rest of the year, most likely due to cellular provider limitations.
The iPhone 4 will become available in black and white, priced at $199 for a 16GB model and $299 for a 32GB model (same AT&T contract, but Jobs said that AT&T would be making a generous upgrade offer). The iPhone 4 goes on sale in the United States, United Kingdom, Germany and France on June 24 before rolling out in other countries over the coming months. Pre-orders begin June 15.
