Richard,
The issue is your somehow using the resolution 326 PPI. Stop doing that.
A pixel is a relative size; the size in absolute units such as inches, millimeters, or points, depends on the resolution. You may have a 1 x 1 pixel image the size of a football field, and a 1000 x 1000 px image the size of a stamp.
In other words, when you have an image with a size in pixel x pixel, that and that alone is your image size in the file, which may then become any size on any of the possible chosen media.

Pretty easy fix. Seams as though everyone above hasn't got a clue....especially the idiots rampling on about the Swedes...Danes...etc..
Here is your answer. Set your canvas to 960 px tall by 600 px wide (960x600). Ok, now go to "Effect" in the menu bar. Then choose "Document Raster Effect Settings". Under "Resolution" choose "Other" and set your resolution to 326ppi. You are done.
A simple explanation for pixels and resolution can be summed up into one phrase "pixel density". A pixel is not a standard unit of measure. A device like the iPhone 4 has a pixel density of 326 ppi (pixels per inch). That is not the standard display resolution of most computers and devices which until recent years was 72 ppi. A device with 326 ppi and one with 72 ppi both with display dimensions of 900px by 600px will have one major difference. That difference is clarity due to more pixels in a square inch. Which is obviously seen when you compare an iPhone 3G to a iPhone 4.

what did you drink before your wrote that ?
Third, what do you expect to happen when changing the "Document Raster Effect Settings". The OP didn't mention anything about using raster effects and unless such effects are used these settings will make no difference.
Forth, while your statement about higher ppi adding more clarity is correct, have in mind that this is valid mostly when comparing the same size with different pixel density, otherwise your general conclusions and logic is wrong. The major difference between different pixel densities is not clarity but the size of the pixels and thus the size of the final image - the clarity is by-product of this. In order to define clarity you have to add the viewing distance in the equation. I have created images for billboards and huge digital murals with pixel density of 10 ppi and I can assure you that all images with such sizes are created with similar pixel density. According to your logic they should be completely unclear and impossible to see comparing to images displayed on i-phones.
When creating for phones and other small displays, in order to see exact details of the final raster image with nothing less or more, the vector graphic in illustrator has to be zoomed to the same physical size on your screen that Photoshop is displaying at 100% zoom using an image with the final pixel dimensions. it is also a good idea to have the image on an additional window zoomed out to the real physical size of the phone screen to get the feel of the final physical dimensions. But because desktop monitors don't have the high pixel density of the phones, the detail will be lost when displaying the real size. Moving a little bit away from the screen to Increase the viewing distance when looking at the larger image with all details in it, can very well approximate the final experience.
