We have battled bravely to bring you this latest piece of news. We have valiantly laughed in the face of possible Malware from the news source to bring to you news of the latest possible PS3 hacking development. A tool is currently in progress that allows you to modify a NAND backup in order to let the PS3 think it has a lower firmware version, so you can later on use an official upgrade PUP file to downgrade to the version you require. The tool has supposedly been tested to patch all PS3 firmware dumps up to 2.10 and requires the Infectus mod chip.
