System and method for downloading information to a mobile device

A computer-readable storage medium having computer-readable instructions for synchronizing supported files between devices without synchronizing unsupported files, the instructions comprising:

• sending, from a mobile device, a synchronization request to a synchronization server in order to initiate a synchronization session for at least one email message, wherein the synchronization request includes a user identifier and a header request, wherein the user identifier identifies a user registered to the synchronization server;
• receiving, on the mobile device, headers of attachments from the synchronization server, wherein the headers indicate an attachment file type for attachments located on the synchronization server that are associated with the user registered to the synchronization server;
• comparing the attachment file type indicated in the headers to a profile of the mobile device sending the synchronization request, wherein the profile includes a list of device types registered to the user identifier and a list of attachment file types supported by each respective device type registered to the user identifier, wherein the comparison includes:
• obtaining a device type identifier of the mobile device, wherein the device type identifier identifies the type of mobile device sending the synchronization request,
• identifying a device type in the list of device types of the profile that matches the obtained device type identifier of the mobile device sending the synchronization request, and
• determining attachment file types located in the list of attachment file types of the profile that are supported by the matched device type;
• sending a supported attachment request from the mobile device to the synchronization server, wherein the supported attachment request includes a request for attachment files located on the synchronization server that were determined as being supported by the matched device type located in the list of attachment file types of the profile;
• and
• receiving, from the synchronization server, the attachment files located on the synchronization server that were determined as being supported by the matched device type located in the list of attachment file types of the profile.

A method for determining supported files for synchronization between devices, the method comprising:

• detecting a synchronization request, from a mobile device, to synchronize at least one email message, wherein the synchronization request includes a device model identifier that identifies a model of the mobile device associated with the synchronization request, wherein the request includes a user identifier that identifies a user registered to a synchronization server;
• identifying email messages indicated by the user identifier that identifies the user registered to the synchronization server;
• identifying attachment files associated with the identified email messages;
• accessing a profile stored on the synchronization server that is implicated by the user identifier of the synchronization request, wherein the profile includes a list of a plurality of device model identifiers, wherein each of the device model identifiers are associated with a list of supported attachment file types;
• comparing the device model identifier of the synchronization request to the profile that is implicated by the user identifier of the synchronization request, wherein the comparison includes:
• identifying a device model identifier in the profile that matches the device model identifier of the synchronization request, and
• determining attachment file types in the list of supported attachment file types of the profile that are implicated by the matched device model identifier of the synchronization request;
• and
• sending, from the synchronization server for receiving on the mobile device, attachment files having the attachment file type determined by the matching in the list of supported file types of the profile.
