Word is a new A6 processor already in early testing in advance of the launch of the iPad 3 in spring 2012. The A6 chip is reportedly a 28nm process (compared with the A5's 45nm), meaning lower energy consumption and higher speeds.
The faster processor would improve the performance of Siri, iOS5's new integrated voice assistant, as well as host of other features, including still and video image capture.

Sprint was first out of the gate with its next-gen network. Verizon has also deployed its 4G LTE network, and AT&T is in the process of rolling out its 4G network now.
There are 4G phones out there (HTC ThunderBolt and Evo, as well as the Motorola Atrix, to name a few), but the big problem so far has been that 4G is a total battery hog. That should change when Qualcomm ships its next-generation 4G chips for phones and we expect to see an iPhone 5 with 4G capabilities.
