It doesn't look different on the outside, but it's full of new stuff on the inside. Powered by the dual-core A5 processor, the Apple iPhone 4S ($200-$400) features iOS5 and its 200 new features including iCloud, as well as an 8-megapixel camera with all-new optics and 1080p HD video recording with image stabilization. And then there's Siri, a scarily-accurate virtual assistant. Just ask Siri a question (by naturally speaking) and it (she?) responds with the answer — no matter how strange or complex your question was. Or just tell Siri to do something — it can make calls, send texts and emails, schedule reminders, make notes, search the web, find local businesses, get directions and much more. The iPhone 4S will ship in black or white in 16GB, 32GB or 64GB models. It'll be available on October 14th on AT&T, Verizon, and now also Sprint. It might not be enough to cure our iPhone 5 sadness, but it might be enough for us to upgrade.
