Apple never really wants to tell us how much RAM is in their devices, but MacRumors is now reporting that the iPhone 4 will have 512MB of RAM. That’s twice what the 3GS and the iPad have and is more on par with it’s competitors like the Evo 4G. That’s good news for everybody.

The iPhone 4 will also have the same processor as the iPad, so if this is true it will also have twice as much memory. Developers will be able to keep more data cached and manage graphics changes more effectively, and for you and me that means browsing without frustrating refresh times and smoother multitasking.

KTF, the Korean mobile operator has just announced their first working 256MB and 512MB USIM prototypes that are designed to be used in your smartphone or 3G. They will provide the user with greater storage flexibility in devices, and we can always use additional memory.

Especially in today’s new phones that have a whole bunch of added functionality. KTF isn’t stopping with these though. They are also working on a 1GB USIM version that will be available sometime in the second half of the year for an unknown price.
