A network supporting user-initiated management of updatable mobile electronic devices such as, for example, cellular phones, personal digital assistants, pagers, personal computers, and the like, permits a user to employ a personal computer (PC) or other device to browse information web portal in order to determine whether an update of firmware, software, and/or configuration information in the mobile electronic device is appropriate. If the user determines that an update is appropriate, or if a content server or a device management (DM) server determines that an update is appropriate, the user may schedule a download of one or more update packages. The update packages may comprise executable instructions for converting a first firmware/software version to a second firmware/software version, and may have associated multipurpose internet mail extension (mime) types. An update may be immediately executed, or an update may be scheduled and performed at a later time according to the user-selected schedule.
