Making the new iteration of the iPhone a World Phone added only $6 to the cost of a GSM-only unit, and updating the camera to an 8MP shooter tacked on $3 to the price of the components. While these are preliminary figures, they tend to back up Apple's decision to bypass LTE or WiMax connectivity, possibly done for financial reasons. After all, with the same amount of space, the HTC ThunderBolt has components valued at $262 according to TechInsights. That includes a LTE chipset, bigger battery and slightly slower processor than what is in the Apple iPhone 4S, no dual-mode support and a lower resolution screen.
A breakdown of the 8GB Apple iPhone 4 shows that Apple is offering the phone with smaller margins. The breakdown of this model comes out to $156 in component cost, but Apple is willing to pass up on some of its profit in order to price the phone at $99 with a signed 2-year contract.
