If you’re a hybrid app developer using PhoneGap/Cordova, you’re probably already tinkering with getting your media queries updated for the larger Apple devices.

If you need to target the specific devices, the following have worked in testing for me (your mileage may vary):

iPhone 6:
@media screen and (max-device-width: 667px) and (-webkit-device-pixel-ratio: 2) { ... }

iPhone 6 Plus:
@media screen and (min-device-width : 414px) and (max-device-height : 736px) and (max-resolution: 401dpi) { ... }

You’ll also need to make sure you’re specifying the necessary new splash screens in your bundles, otherwise you’ll revert to scaling.

Give it a shot!
