It took a while, but preorders for Apple's recently announced iPhone 4S handset are now live.

In an interview with Eurogamer, Donald Mustard (of chAIR Entertainment) recently noted that Apple's iPhone 4S boasts 512 megabytes of RAM.

Here's something a little spooky. Around the mid-90s, Apple made a video outlining a a product former Apple CEO John Scully talked about in his 1987 book, Odyssey. As you can see, the video appears to outline a computer equipped with software just like the recently announced Siri.

U.S. customers, there is now a third place to buy the iPhone. Beginning October 14, Sprint will offer Apple’s latest iDevice, the iPhone 4S, along with AT&T and Verizon. Best of all, the No. 3 U.S. carrier is keeping its unlimited plans in place.

Apple's iPhone 4S might look like its predecessor, but the handset's exclusive Siri service sets it apart from every other smart phone on the market. However, Japanese Apple fans aren't going to be able to take advantage of the feature initially because, to begin with, it'll support just English, French and German. But that's not all Siri has to contend with in Japan - even its name is something of a joke.

Millions of buyers will make iPhone 4S purchases next week without once asking an Apple representative a question about the new handset. Still, when the questions do come, Apple will be ready. 9 To 5 Mac has uncovered internal documents being used to explain the iPhone 4S to their employees, so they can explain it to you.

Not surprisingly, Samsung plans today to file preliminary injunction motions against Apple over its new iPhone 4S. The South Korean-based company is hoping to convince courts in Paris and Milan, Italy to stop the sale of Apple’s next-generation handset before they begin, according to CNN.

The folks at The Verge were the first to highlight the hardware differences between the iPhone 4S and its predecessor by releasing the attached table. Most interesting, mainly because Apple didn’t mention it at yesterday’s iPhone event, is that the iPhone 4S weighs three grams more than the iPhone 4. Will this extra weight cause some to bypass Apple’s latest wonder? Probably not.
