The iPhone 4 is Apple's most expensive ever phone to make short of the original phone itself, a price breakdown by iSuppli has found. A 16GB example costs about $187.51 in raw parts; the bill is less than the $223 of the 2007 original but more than the $173 iPhone 3G and the $178.96 iPhone 3GS. Most of that cost increase is attributed to the LG Display-built 960x640 IPS screen, which is estimated to cost $28.50 all by itself.
