Abstract: A wireless communications system may include a plurality of mobile wireless communications devices each having a subscriber account associated therewith including a respective personal identification number (PIN) and a device identification (ID). Each device ID may have associated therewith a device capability set from among a plurality of device capability sets. The system may further include at least one electronic mail (email) server including a database of subscriber accounts and for sending emails to and receiving emails from the mobile wireless communications devices based upon the PINs and device IDs. The at least one email server may compare a given PIN and device ID, based upon a communication from a given mobile wireless device, with a corresponding PIN and device ID for the corresponding subscriber account in the database, and update a corresponding device capability set for the corresponding subscriber account based upon a discrepancy.

Abstract: A wireless communications system may include a plurality of wireless communications networks and a plurality of mobile wireless communications devices for sending and receiving wireless electronic mail (email) messages over the wireless communications networks. The system may further include a resource deployment server for storing a plurality of resource deployment packages (RDPs), where each RDP includes deployment content and deployment instructions therefor relating to sending and receiving email messages. The resource deployment server may also be for dynamically deploying RDPs to the wireless communications networks to update deployment content thereof based upon the respective deployment instructions.

Abstract: A system for referencing alternative images for rendering presentation pages includes a server, which includes an extensible stylesheet transformation (XSLT) module having an extension. A storage medium contains the image. The XSLT module is operative for calling the extension to determine where an image exists in the storage medium and rendering the image image into a presentation page.

Abstract: A system transforms application data into presentation information. A server includes an extensible stylesheet transformation (XSLT) module and a Java extension. A cache contains a template for a presentation document. The XSLT module is operative for calling the template from the cache into the presentation document through the Java extension of the XSLT module.
