    I know the recent versions of OS X have memory compression to help make more of your ram. Now I found something in ios logs under privacy/diagnostics and usage. I have one "jetsamevent" log showing all my processes AND notice the reference to compressed pages. Has Apple confirmed they added this anywhere?

    Really? Well I just have an iPhone 5. Maybe ios 8 expanded this feature? I remember seeing speculative threads on whether ios would get memory compression awhile back so I assumed we had to wait for 8 for it.

    Im sure it does have memory compression but I've been trying to find the article I came across last year that talked about how the 64-bit architecture in the A7 (& now A8) can use local storage for as RAM....
