iPhone 4G could get the iPad Apple A4 chip?

After the release of the “interesting” iPad, there have been rumours that the new iPhone 4g could get the same 1GHz Apple A4 chip. Apple claims that using the new A4 chip would drastically improved battery life – for the iPad, Apple claims to get 10 hours of battery life with it, along with a month of standby.
Currently the iPhone 3GS has the ARM Cortex A8 CPUs and PowerVR SGX GPUs chips from Samsung.
