I’ve been using the Yell.com Mobile application for about a year now and find it very handy for finding telephone numbers of businesses. Now Yell.com have added a new mobile application to their range called Yell Maps.
Its much the same concept as the Yell.com Mobile, but it starts as a map based search rather than a business name search. For full details visit http://www.yellmobile.com/index.html
Try it out and download from your mobile using http://mobile.yell.com/uk
