The great iPhone speed comparison - it's closer than you think
This is interesting if you like iPhones. And we do, so we think it's very interesting. It's a side-by-side comparison of all four iPhone models to date, showing how performance has improved over the past three years.
It's not a thoroughly scientific trial; for example, the handsets weren't necessarily running the most optimum OS available. According to the producers, the original iPhone was running 3.1.3, the 3G 3.1.2, the 3GS 4.01 and the iPhone4 was running 4.0.
What's very striking, apart from refinements like screen quality, is how the iPhone 4 isn't all that much of an improvement on the 3GS in terms of operating speed:
