Like Apple's various iPods, the iPhone isn't designed for quick, easy disassembly. I'm sure the process would go more smoothly with specialised tools, but I expect it would still be a delicate, time-consuming job.
After examining the iPhone for several minutes, I selected the black, plastic antenna cover as the appropriate starting point.
Using a very thin knife blade, I gently pried off the iPhone's black antenna cover. I started with the area just above the dock connector and worked my way around the cover.
