The Omnia ONE has two built-in software banks. When a software update is performed, the new software is loaded into the bank that is currently not in use. By loading a different style (downloadable free from OmniaAudio.com/software) into a software bank and then booting the unit from that bank, the unit will be running the new style. In fact, this procedure is exactly the same as for a software upgrade. Please see the Omnia ONE user manual for full instructions.
