During last week's Let's Talk iPhone event, Apple unveiled the iPhone 4S with plenty of information on its specs -- Siri, up to 64 gigabytes of storage space and a dual-core A5 chip. However, one thing on people's minds that Apple didn't mention for some reason was RAM space. 

Rumors have previously suggested that the iPhone 4S would get a boost up to 1GB of RAM, but new reports point to only 512MB of RAM, which is what's currently offered in the iPhone 4 and the iPad 2.

According to MacRumors, there have been two separate instances since the iPhone 4S launch that suggest the device would not be getting the long-awaited boost in RAM. The first comes from an interview with Epic Games creative director Donald Mustard. In discussing the company's development of Infinity Blade 2 for the iPhone 4S, Mustard let it slip that the iPhone 4S sports 512MB of RAM.

I'm still shocked that, with the iPhone 4S, I'm literally running around with a 1080p video camera in my pocket, with an eight megapixel camera, 64GB of hard drive space and an A5 chip with 512MB of memory, said Mustard. This is a really powerful computer, right?

One could consider Mustard's mention of 512MB of RAM as fact, since top-tier game developers were given early iPhone 4S hardware for game development and optimization.

The second instance comes from a Chinese blog, AppVV, where a poster claims to have already obtained an iPhone 4S. In the discussion thread, the poster confirms that the iPhone 4S still contains 512MB.

The iPhone 4S will be released for Sprint, Verizon, and AT&T on Oct. 14.
