So I'm having a clear out and I found an old phone and charger that I used to use on PAYG.

I want to get it on ebay instead of letting it sit around collecting dust.

I'm wondering if anyone knows how to reset it and delete all my data? I've searched google for a while and found different links to getting it unlocked in Canada and the actual user manual which tells me to go into the security menu and there should be a reset option in there but I cannot find it.
