iPhone 4 Packs 512 RAM, WWDC10 Video Session Reveals

Apple is providing more than 100 WWDC10 video sessions and slides for free via iTunes U, including the Steve Jobs keynote address, which features Apple’s CEO and fellow execs introducing and demoing the iPhone 4. One session in particular - “Advanced Performance Optimization on iPhone OS, pt 2” - reveals that Apple has packed 512MB of RAM into its next-generation smartphone.

The session videos are available in both small definition (SD) and high definition (HD). Presentation slides are downloadable in PDF format, while session-related sample code is also being made available, all free of charge.

The effort is likely an indirect apology to the developers who didn’t get a chance to book a spot at this year’s conference. WWDC10 sold out in record time this year, similar to last year. However, in 2009, the Mac maker charged developers who didn't pay for a WWDC ticket $500 to access the session videos. Now, more than 100 individual sessions filmed at the 2010 Worldwide Developers Conference are available to anyone who has signed up in any of Apple’s developer programs, through iTunes U.

Interestingly, Session 147 - Advanced Performance Optimization on iPhone OS, pt 2 shows that iPhone 4 boasts twice the amount of RAM available in iPhone 3GS or the iPad. Apple’s tablet packs 256MB of RAM, whereas iPhone 4 has been confirmed to feature double that amount of memory - 512MB. A screenshot posted by Macerkopf.de (available to the left) verifies the larger 512MB RAM capacity of the iPhone 4.

The news contradicts photographic evidence of an iPhone 4 prototype disassembled in Vietnam, yet is on par with a Digitimes report that confirmed last month the following iPhone 4 specs: 960x640 screen resolution; thinner display; 512MB of RAM. The phone’s memory is packed inside Apple’s new A4 chip. It is believed that Apple’s Steve Jobs did not mention any such tech specs at the WWDC10 keynote because the company was forced to under-clock the A4 chip in order to address battery life.
