Methods and systems for scrolling through content of media. An example method performed on a cell phone receives an index of segments from a server over a cellular network and a public data network. The received segment is presented based on the received index of segments. A request for a media file associated with the presented segment is generated and sent, if a user selection signal is received. The index of segments includes information that associates a preselected segment of a full media file with the full media file. A request for a segment associated with the received index of segments to the server is generated and sent and the requested segment is received from the server based on the request before presenting. The requested media file is received and presented after the server processes the request for the media file.
