  • iPhone 4 Has 512MB RAM

    Confirmation that the new iPhone has twice the RAM of the iPad or the iPhone 3GS has come from a recently released video of a developer session at WWDC 10. MacRumors first reported the revelation, which is the first acknowledgement from Apple that iPhone 4 has 512MB of RAM.

    For a company that loves to dish out specs (highest pixel density of any smartphone, most energy efficient desktop, etc.), Apple sure is reticent when it comes to the amount of RAM in an iPhone. They've never publicized the memory specs, ever, and so we've had to wait for teardowns or leaks to find out, for, example, that the 3GS has 256MB of RAM. In the case of the iPhone 4, the assumption has been that the production phone has 256MB RAM, because that's how much memory was installed in the "lost-and-found" prototype when Gizmodo cracked it open, and how much the A4 chip on the iPad has.

    Video of the session where the RAM capacity was revealed, Advanced Performance Optimization on iPhone OS part 2, was recently released to registered Apple developers for download via iTunes, but is not presently available due to high demand.

    As MacRumors notes, this may explain why iMovie will only run on iPhone 4, and not the iPad.

      The iPhone 4 really has 512MB ram???
      I'll be waiting anyway for a week until Apple get some in stock so I hope to see people confirm this.
      Either way I'm getting the iPhone 4 and iPad 2.

      this is pretty good news and if confirmed will shut up all the people complaining about it "not having enough/same memory as other smart phones that are out now"

      Man this is hot hot stuff!!

      Here's to hoping that I don't get shafted come Thursday morning!! Sending out my 3g tomorrow to my eBay buyer

      I can't even imagine what it will be like to not have to worry about memory issues. Having skipped the 3gs, and having a life with 128mb for 2 years, this is going to BLOW MY MIND!!

      Wow. This just completely murders the HTC Evo. Haters, you can shut your mouth now. SOO glad I pre-ordered my 32GB i4.

      So glad my pre-order went through. I'm stoked for this. My first launch iPhone even though I've owned every model so far. Hopefully the jailbreak doesn't take too long

      Good god I hope this is correct! I just got some traffic tickets which ate all my money from my recently sold 3G, and was gonna wait until Feb for my iPhone 4.. but now I'm probably gonna sell the 3GS too and get this.. I've wanted 512mb for so, so long!!

      I am debating the same thing Doran.

      Honestly I think it depends on which of your options is more "low pro". In my case I think it's AT&T, although I an worried that their stock will be limited compared to Apple.

      Fortunately I have a reserve at the Apple store as a backup plan
