By now, the specs on the Samsung Galaxy Nexus are already publicly known, but what other magic is hiding within all the wires and circuitry? To find out, we've enlisted the help of developer Francois Simond (SuperCurio) to break down as many of the inner components of the Android 4.0-loaded device as possible. And while there isn't anything particularly earth-shattering revealed here, we at least have a better idea of the kind of wizardry taking place underneath that bedazzling HD display. Read on with us to learn all of the deliciously nerdy details.

Here are a few things we unearthed in the Galaxy Nexus:
