It dependes what you mean by "context of use," there are several papers that look at accruately predicting the context a mobile device is currently in. This year at CHI there was a paper where they tracked where phones were kept (pockets, tables, purses) using interviews and phone data. They were able to accurately determine the context of phones using existing sensors.
Phoneprioception: Enabling Mobile Phones to Infer Where They Are Kept

Is this what you are looking for in terms of context?
Typically (considering adaptability) context of use means to consider the user, the platform and the environment. Then, when there is changes in the platform, it can be considered the mobile devices. Sometimes it is also included social relations. The Cameleon framework supports changes in the context of use (http://www.w3.org/2005/Incubator/model-based-ui/XGR-mbui-20100504/), I also recomment to look at the Serenoa Project deliverables (http://www.serenoa-fp7.eu).
