According to a Red Bend spokesperson, vRapid Mobile is a new and enhanced superset of the company's widely used VCurrent Mobile FOTA software.

Calling the new approach Software Components Over-the-Air (SCOTA), Red Bend says that vRapid Mobile can update the following components:

* Embedded applications such as messaging clients, web browsers, homescreen clients, and media players
* Middleware and service enablers including Java Virtual Machine, Flash Lite, position location software, media codecs, SIP and IMS clients, and digital rights management (DRM) agents
* Device features like Bluetooth profiles and multimedia and 3D graphics engines"
