It doesn't even run on the iPhone 3GS? Also, the iPhone 2G and 3G have identical processors, so I'm not seeing where a speed difference would come from...
First 2 iPhone generations had a 600 Mhz ARM 11 CPU but they only ran at 400 Mhz. iPhone 3GS was about twice as fast with a much better Cortex A8 CPU and a 600 MHz clock.
Besides he said it's working even faster on iPhone 3GS than on a Droid 1 (same CPU and clock). Did you even read the comment?
Secondly, my point was about the iPhone 2G vs 3G (not 3GS), in reply t "it runs incredibly slowly on a 2G, but quite reasonable on a 3G". They -- as you said -- have the exact same processor, so it can't really run very different on one or the other. (In fact, I have it on both right in front of me, it seems about the same running iDroid.)
CPUs today are a lot less based on raw MHz/GHz and more about the technologies in which they achieve them. This can be easily seen with some single-core CPUs out-performing dual core and a few quad core CPUs. Who cares if you have a 3.2 GHz quad core CPU if this other single-core CPU at 2.8 GHz is better? While these situations aren't too common, they're prime examples of how raw speed doesn't matter.
