This iPhone is comparable to the release of the iPhone 3G, they're best upgrade prior. Changing of network speed is the biggest upgrade you could ask for. If people don't buy it it asap, they'll be sure to get one when they see how fast their friends navigate websites and network apps.
Except that, given the first benchmark results, the iPhone 5 almost trippled the hardware speeds in comparison to the 4S and features a new design.
The 3G didn't feature much more compared to the classic except 3G. So it's actually not comparable and this release is much bigger. But still, haters gonna hate...
I for myself can't wait for Friday to arrive
