iPhone 4 has 512MB of RAM
How much RAM does iPhone 4 have? According to confirmed reports by MacRumors, iPhone 4 has 512MB of RAM which is twice the amount of memory in both the iPhone 3GS and iPad at 256MB. MacRumors goes on to suggest this is why the upcoming iMovie app will only run on iPhone 4 and not on past iPhone’s or even the iPad.
This is interesting to know because now iPhone 4 has the same A4 processor as the iPad, but twice as much memory and a significantly higher quality screen. Will the amount of memory on the devices effect how well they run iOS 4? We already know that older iPhone models will not get all the features of the new OS. And will iPad get a significant upgrade sometime this year to a retina display and more memory?
