Apparently,iPhone runs iOS, and Galaxy runs Android. and the hardware configuration on Galaxy is better than iPhone, but iPhone still the best smartphone so far.
The biggest problem with the Galaxy Mini is the small inphone memory. "Pathetic". However as an iPad owner and occassional iPhone user I'd stick with Android by choice.
So most people use Galaxy S2, and now there is Galaxy note 4G LTE with huge display and bigger memory.
Samsung Galaxy is Android based iPhone is IOS and iPhone 4s have voice recognition software called siri and no other phone have such quality voice recognition software.
