One of the rumors surrounding the upcoming iPhone 4 has now been confirmed – apparently, the new Apple phone will boast a whole of 512MB system RAM, which is twice as much as the iPhone 3GS that came out last year, and more notably, twice as much as the iPad tablet. We know, it can be disheartening news if you happen to be an iPad user who bought the Apple tablet recently. But the additional memory will supposedly give the iPhone 4 much more robust multitasking.
We had heard that Apple confirmed this 512MB figure during one of the WWDC sessions last week, and have now verified this. The added RAM should help overall performance and multi-tasking on the new iPhone 4. It could also explain why the iMovie App that Apple introduced at WWDC will only run on the iPhone 4. Apple has said iMovie will only run on the iPhone 4 and not the 3GS or even the iPad. It seems conceivable that it actually makes use of the extra RAM offered by the iPhone 4.
Furthermore, it seems that the new change is aimed exactly at improving the iPhone’s multitasking performance, according to an Apple representative. With the old 256MB of memory, a lot of time and power went wasted into memory management, which will no longer be an issue. Some of the new features of the iOS 4, which will be launched on Monday, will allow programs such as Skype and Pandora to accept incoming VoIP calls, or play music while another application is taking focus in the foreground.
The mobile operating system upgrade will also let users quickly switch between in-memory applications using an “app tray” that appears when users double-tap the iPhone’s home button. The 256MB mark appears to be the minimum required for iOS 4 to multitask; while iPhone 3G owners can still upgrade their phones to the new OS, they won’t get multitasking.
However, this confirmation of 512MB in the iPhone 4 contradicts evidence gleaned from photographs of prototypes leaked by the Gizmodo technology blog in April, and a Vietnamese site last month. In both instance, experts said that the next-generation iPhone would probably have only 256MB, the same as in the iPhone 3GS and the iPad.
