Underneath our clothes we're all naked, but underneath the iPhone's classy casing are a number of intriguing circuitboards and components.  ifixit.com seem slightly more excited about opening up their iPhone than they are about, well, making calls on it, and so they've been quick to undo the sixteen screws holding it all together and have a good poke about inside.

Unlike Think Secret, who broke their iPhone when trying to seperate parts of the logic board, ifixit managed to spread it all out over the table without permanent damage to any of the components.  Now to see if they can put it back together!

So far they've identified a Skyworks GSM/EDGE power amplifier, ARM 339S0030 which they believe to be the baseband processor and Samsung K9HBG08U1M which could be the video processor Edit: commentor reinharden helpfully tells us that it's actually a 4GB flash module.  Hopefully the fact that the antenna covers the whole black plastic region on the back-bottom section of the handset should mean that signal strength is rarely an issue.

The battery is soldered directly to the logic board, and is a 3.7V LiIon Polymer unit.
