The Good Apple's iPhone 4S has a faster processor and an upgraded camera, all the benefits of iOS 5, and a useful and immensely fun voice assistant. Call quality on the Sprint model is admirable, and the data speeds, while certainly not 4G, get the job done.
The Bad It's about time we get a larger screen.
The Bottom Line The iPhone 4S isn't the king of cell phones, but it's part of the royal family nonetheless. Even without 4G and a giant screen, this phone's smart(ass) voice assistant, Siri, the benefits of iOS 5, and its spectacular camera make it a top choice for anyone ready to upgrade.
