final price tag to build an iPhone 5 turns out to be $167.50 — making it Apple's most expensive phone ever. Some of the
most impressive components of the iPhone 5 actually don't wind up being very expensive on their own. UBM TechInsights estimates that the new, thinner 4-inch touch display costs Apple $18 with the touch screen glass costing another $7.50. The camera runs about $10, the wifi/bluetooth/GPS costs $4, and the battery only runs $3. The most expensive part of the phone is the new A6 processor, at $28 each.
