The type of phone, phone OS, computer or computer OS that a person uses has no correlation to intelligence. Some very intelligent people have more important things to do than use every feature of a device if they have no need for that feature or mod the device or OS for no reason to them. Just because someone roots an Android device, it does not automatically make them more intelligent than someone who does not or uses an iPhone or just a simple phone. If someone needs to show their intelligence by bragging that they mod something just for no particular reason then perhaps they are not quite as intelligent as they think they are. Some people need to impress their friends by owning an iPhone. Others have to impress their friends by showing that they rooted and ROMed their Android phone. If they were truly intelligent they would not have to prove it in those ways. Do you think that Einstein would have modded his phone if they existed back then? I doubt it. He had much more important things to accomplish.
