I just sold my old BB 7130. Before i give it out, i want to make sure i clear personal info from it.
how can i do that?
i.e.
1. gmail account? - how do i clear?
2. other memories
3. passwords - i've deleted all entries, but is it truly removed? or do i need to format / flash memory?

finally, if i want to just remove everything and restore factory settings, how can i do that?

Thanks!
