Add Pivotal to the list of tech players adding mobile services to its development platform. Last week, the company announced Pivotal CF Mobile Services, which aims to enable developers to build push notifications into their applications; an API gateway to let them incorporate an array of third-party services; and data synchronization to give those apps access to lots of data types. The service, which builds on the Pivotal acquisition of Xtreme Labs last year, will be available sometime this quarter.
