I know a software available for iPhone, which is called
Enterprise wizard CRM. It gives users contact, task, group, sales and project management, as well as group messaging and reporting functionality in one easy-to-use interface that is now compatible with the iPhone's Safari web browser.
CRM for iPhone is seamlessly integrated with Enterprise Wizard CRM, which may be can already be run in Google Apps, Netvibes, Windows Live and Pageflakes.
