Rockbox is an open source firmware for MP3 players provided by the likes of SanDisk, iriver, Archos and Toshiba. Ports are now available for a range ‘s. A port is now available for Android which plays tunes without stutter and includes neat touches like gap-less playback and cross-fading.
The UI is a little basic at the moment but it’s in the early stages. Download the APK for your device and install it – preferably to your SD card as it’s a little large.
