Unfortunately, the standards for LTE have not been established yet. That is why you have everybody running around talking 4G even though each carrier uses a different technology and delivers different speeds.
Do you know how small 28nm is? wow.

Report: Samsung and Apple Quadruple Application Processor Production
As Apple devices get more popular—or, rather, more widespread as a result of the company’s imminent iPhone launch through mobile carrier Verizon and the much-expected debut of the iPhone 5—someone has to make the chips that actually power the devices’ features. Apple seems keenly aware of this fact, as the company is allegedly boosting its application processor order from Samsung from 5,000 monthly sheets of chips to 20,000.
...
Samsung has been Apple’s partner in creating the application processors that power Apple devices for some time now, and the two companies worked together—in a fashion—to develop Apple’s A4 line of system-on-a-chips. Samsung and Intrinsity initially collaborated to create Hummingbird, a revamp of ARM’s Cortex A8, which many consider the groundwork for Apple’s A4 processor after Apple purchased Intrinsity outright in April of 2010.
