As expected, the moment Apple's new iPhone 4 hit the streets, iFixit nabbed it, took it back to the lab, and proceeded with an iPhone 4 teardown. Especially exciting:
We have confirmed that the iPhone's A4 processor has 512 MB RAM, unlike the iPad's more limited 256 MB. This decision may have been made fairly late in Apple's development cycle, because early leaked prototype phones only had 256 MB.
UPDATE: Looks like the Retina Display may indeed be protected by Gorilla Glass!
The front glass panel of the iPhone is constructed of Corning Gorilla Glass, a chemically strengthened alkali-aluminosilicate thin sheet glass that is reported to be 20 times stiffer and 30 times harder than plastic.
Gorilla Glass holds many advantages as the iPhone 4's front panel including its high resistance to wear and increased strength from a strengthening process.
The teardown is still underway and we'll update when they're done, but in the meantime you can catch the action via the link below.
