The Latest iPhone 5 Rumor Is That It Is Going To Save The US Economy

JP Morgan analyst Michael Feroli has written a note suggesting that Apple's iPhone 5, to be announced tomorrow, could, by itself, grow the GDP between .25% and .5% in the fourth quarter.

The math in six steps:

1. Feroli says JP Morgan's other analysts say Apple will sell about 8 million phones for $600.
2. Imported components should cost around $200 per phone, netting the GDP $400 per gadget.
3. $400 x 8 million = $3.2 billion in GDP.
4. $3.2 billion x four quarters = $12.8 billion.
5. $12.8 billion = 33% boost.
6. If the phone sells even better, the number gets closer to .5%.

.5% is a big boost. Most analysts predict the GDP will grow 1.5% to 2% in Q4.
