I am trying to implement alternate layouts for both the iPad/iPhone and older iPhones as well.

I have established that the best method is to use `@media` from the CSS3 spec.

As such these are my media queries at the minute:

```
@media screen and (max-width: 1000px) { ... }

```

Above is for small desktop and laptop screens.

```
@media screen and (max-width: 700px) { ... }

```

Above is for the iPad and VERY small desktop/laptop screens.

```
@media screen and (max-device-width: 480px) { ... }

```

Above is for iPhone 3GS- and mobile devices in general.

However, the new iPhone 4 with Steve Jobs's all-singing all-dancing "retina" display means that it has a pixel ratio of 2-1 meaning 1 pixel actually appears to the browser as 2x2 pixels making its resolution (960x640 - meaning it will trigger the iPad layout rather than the mobile device layout) so this requires ANOTHER media query (only so far supported by webkit):

```
@media screen and (-webkit-min-device-pixel-ratio: 2) { ... }

```

Now, the thing is... I want my nice shiny new iPhone 4 layout amalgamated with the iPhone 3GS and mobile device layout as they will both have exactly the same inner CSS code,

Therefore making my question;

**How do I create an `@media` rule that points both the iPhone 4, 3GS and other mobiles to the same styles?**
