“The original iPhone and iPhone 3G contained 128MB of RAM, while the iPhone 3GS was boosted to 256MB of RAM. Similarly, the iPad contains 256MB of RAM,” Arnold Kim reports for MacRumors. “This discrepancy offers a technical explanation why Apple is not supporting iOS 4 features such as multi-tasking on the original and 3G iPhone — there simply isn’t enough RAM.”

Kim reports, “We have since heard that the upcoming iPhone 4’s RAM has again been upgraded. This will bring it to a total of 512MB of RAM, twice as much as the 3GS and iPad.”

“The added RAM should help overall performance and multi-tasking on the new iPhone 4,” Kim reports. “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.”
