An acronym for "Over The Air" update, an OTA update generally refers to a firmware upgrade that is distributed to phones or other devices wirelessly, usually by a cell carrier or device manufacturer. This is sometimes also referred to as FOTA ("Firmware Over The Air"). Android has supported OTA upgrading since at least version 1.5 (Cupcake).
