Everybody’s favorite rumor site The Register has published an article explaining the details of a potential Sony PSP update, which is based on a leaked copy of an early version of the update code. According to the article, the update would include a web browser, an email client, a calculator and possibly a word processor and spreadsheet.

Here’s a clipping from the story:

At this stage, the translations from the original Japanese exploration of the alleged PSP update file doesn’t make it clear whether these are fully functioning office apps - or simply readers put in place to handle emailed attachments. Given the device’s nature, we suspect that latter, but early talk of a PSP keyboard accessory has led some observers to suggest they’re the real thing.

The article stems from reports that an unofficial PSP update was found on a web domain owned by Sony. It is expected that Sony will release the update before the European and North American launch of the PSP.
