Systems and methods are descried for providing connectivity to portable electronic devices, such as a cordless telephone, for the purpose of upgrading software features. In a preferred embodiment, portable electronic devices can be connected to a conventional household audio player via an audio input/out interface in the device to receive encoded data signals modulated in an audio band. The audio player can playback an audio signal stored in any of several different formats, including compact disc, audio cassette tape, MP3 file, or streaming audio, and can be physically connected an audio jack in the portable electronic device via a conventional audio cable.
