In Pictures: Inside the Apple iPhone

This view shows the top of the applications circuit board, home of the iPhone's core components. The flash memory is among the most expensive elements in the iPhone--even with flash prices having fallen almost by half since the iPhone's unveiling in January. "Memory pricing has fallen right through the floor," says iSuppli's Rebello. The 4GB Samsung NAND memory costs $24 (seen here), while the 8GB costs $48. The Samsung memory uses multi-level cell (MLC) technology, which stores more bits per cell than single-level cell (SLC) technology, but also means you'll have higher power consumption.
