Hi guys, I have just sold my n900 - before i ship it off I wonder if someone could provide some advice on the best way to make sure any data on it isn't recoverable - particularly photos. I'd rather not have to factory reset / wipe the thing.

For example, if I was to delete a large portion off the hard drive of my computer, some of it could probably be recovered with special software - I assume this would apply to the HDD within the N900?

Any advice here appreciated.
