Summary

Thanks to my coworker for lending me his phone for a few minutes (he waited in line for 9 hours yesterday when it first went on sale!).

This is quite an improvement over the iPhone 3GS running iOS4, which ran the SunSpider test in 13787ms. The iPhone 4 ran the same test in 10669ms, which makes it ~22% faster head-to-head.

Processors

The iPhone 3GS has a Samsung S5PC100 ARM Cortex-A8[5] 833 MHz (underclocked to 600 MHz), while the iPhone 4 has an Apple A4 1GHz (likely underclocked to an unknown speed).
