[Updated with AT&T "early upgrade" pricing.]
Steve Jobs announced the new iPhone 4 on stage at Moscone Center today, and while there were few surprises after months of speculation, leaks, possible thefts and teardowns, there were a number of interesting details revealed at the WWDC 10 keynote speech. The phone will be available on June 24 in five countries: the US, France, Germany, the UK and Japan. Pre-orders start on Tuesday, June 15, with the 16GB iPhone going for $199 US and the 32GB for $299. Update: if you're an AT&T customer in the middle of your contract, you can get an iPhone 4 at "early upgrade" prices of $399 for the 16GB model and $499 for the 32GB.
The iPhone 4 is 24% thinner than the iPhone 3GS: at a mere 9.3 mm thick, it is the "thinnest smartphone ever" as Jobs bragged. The front and back of the case are made of glass: a surface engineered to be "30 times harder than plastic" according to a video shown at the end of the keynote. As expected, the new iPhone is based on the A4 processor running at 1GHz. Though Jobs didn't announce details, teardowns showed that the phone has 256MB of RAM built into the system-on-a-chip. The new model - which many thought would be called the "iPhone HD" - has a sharp new 960x640 IPS LCD touchscreen - called the "Retina Display" - that delivers an industry-leading 326 pixels per inch, four times the pixel density of the 3GS. Steve Jobs claimed that the limit that the human retina can perceive is 300 pixels per inch, making the iPhone 4's display "like text in a fine printed book." With a 3.5 inch display that has 78% the number of pixels on the iPad's 9.7 inch screen, Jobs had some reason to crow that "once you use a Retina Display, you can't go back."
The phone has a 5-megapixel camera on the glass rear case with a backside illuminated sensor and an LED flash for low-light photography. The imaging hardware uses 1.75-µm pixel size and 5x digital zoom with tap-to-focus controls for video and still pictures. The iPhone 4 is capable of recording 720p HD video at 30 frames per second and will allow built-in video editing with iMovie for iPhone available for $4.99. And as demoed in the "one more thing" segment at the end of the keynote, FaceTime video conferencing, from iPhone 4 to iPhone 4, will be supported, using either the 2 megapixel front-facing camera or the rear camera … but using WiFi only.
The iPhone 4 has an improved battery that Jobs says will allow "7 hours of 3G talk, 6 hours of 3G browsing, 10 hours of WiFi browsing, 10 hours of video, and 40 hours of music." With a noise-cancellation microphone at the top, the iPhone 4 has noise suppression for improved call quality. It uses the stainless-steel band around the edge as an integrated antenna and has quad-band HSDPA for 7.2Mbps downloads and HSDPA for 5.8 Mbps uploads (where HSPA is supported). The new phone uses a micro-SIM card - just like the iPad - which is inserted through a slot on the side.
One cool, and pretty much unexpected, addition is that the phone now has a true gyroscope for pitch, yaw and roll, which is tied into the accelerometer for gravity sensing (which way is up) and the GPS chip for location. Jobs demoed a 3D Jenga-like game, which moved as the phone moved. The possibilities for app development are really huge here, especially - but not only - in gaming.
Check your upgrade credit if you're an AT&T customer… as Jobs announced from the stage, AT&T will give credit to anyone whose contract will come up any time in 2010.
