While Apple continues to break our jailbreaks and 3rd party apps, they are working on the iPhone to make it faster and more battery efficient. The recent update of firmware v1.1.2 boosts the iPhone's clock speed from a CPU Frequency of 400Mhz, and a Bus frequency of 100mHz, to a CPU frequency of 412Mhz, and a Bus frequency of 103Mhz. This information can be obtained via SysInfo in installer.app.

While you may not notice a difference, Apple is definitely trying to figure out ways to keep the battery life, and make the iPhone perform faster. Could this possibly be for the upcoming SDK release in order to make sure the phone will run most 3rd party apps? Hopefully, and we'll see come February.
