Is it possible to access a list of wifi networks my iPhone has used?

I understand I may have to jailbreak my phone to access this, but is there a way to view a list of networks my iPhone has remembered and get info on the date they were last accessed?

I know there are some apps that allow you to view all the stored passwords for previously accessed networks but I'm also interested in seeing the date they were last accessed.

Thanks in advance of any help you can give.
