Mobility for SAP provides CRM, ERP and Workflow integration on a BlackBerry, Android and iPhone/iPad Smartphone (where iPhone/iPad is available as prototype today).
It enables the user to mobile search, read, update and create data.
It is based on "lean mobile": a standard client on the smartphone executes webservices in the backend system. So no additional components or midleware is needed. Implementation on a test system is possible in some hours.
Customer specific enhancements can easily done with pure ABAP without time consuming develpment on the smartphones.
