Flash Maps API
MapQuest offers both a desktop/web and mobile version of the Flash Maps API (for use with Adobe Flash Builder using Flex). The mobile version of the API is streamlined for performance, as well as providing support for touch gestures.
iOS Maps API
The highly anticipated iOS Maps API with multi-touch gesture support makes its debut and can easily be implemented for development of native applications on the iPhone, iPod Touch and iPad. As it is still in Beta, don't forget to provide feedback and help us improve the API!
Developing interactive maps that work across a variety of mobile devices can be a headache. We have seen the issues up close through our development of both mobile web and native applications for our consumer products. Now you can skip the headaches and go straight to the solutions.
If you develop like us, the first thing you look for is sample code. We have featured sample code embedded inline in our developer guides so that you can run samples while you read the docs. Here are some popular developer pages with interesting samples embedded.
