Fixed an issue that caused the compass to show an incorrect heading when the device was in landscape orientation.

I've updated the app for modern devices, and made some performance improvements.

Support for the latest devices and iOS versions.

All Speed now looks good on all devices.

- support for 4 inch screen (iPhone 5)

- upgraded graphics for retina display on the new iPad

- All Speed now remembers whether you were using digital or analog speedometer between launches.
- Greatly enhanced clockface-switching mechanism for analog speedometer.

- Digital Speedometer. Tap Speedometer to toggle between digital or analog speedometer.

- Streamlined clockface-switching for analog speedometer.
- Fixed a glitch in the compass-graphics. (Thanks to Remco for pointing it out).

Now you can choose to display your speed in metric units (km/h) or imperial units (mph).
To change the units, go to the settings app and find All Speed in the list of apps.
