Umm ... yeah... wasn't THAT long ago. I was a field service engineer, repairing computers in the late '70's. This was before the advent of the desktop computer and pc, systems were the size of your refridgerator. A 10 MB hard drive platter was larger than a vinyl LP record and RAM was 'Static RAM' coils.I remember RAM doubler for computers. This is a long long time ago, it came out in the end, they were just a scam. I don't like software that says it extends memory, battery etc, when it itself sits in memory making threads, taking up memory etc. I might be wrong but smoke n mirrors.
Remember jd does wake the phone every 10mins or so to activate data to check for emails etc, that would be why its thereI have noticed under partial wakelocks the JD service is always leading the list on my Nexus. Not sure if I get better battery life with or without it (still playing).
