quick search took me to this thread...
http://forums.windowscentral.com/win...mia-800-a.html which brought me to this
app, which i've never used myself but it says it provides the functionality you are looking for but didnt actually let me try it out so i tried this
app instead and it seemed to do the trick. it saved them to my phone or to onedrive as a .txt. then just change the ext to csv and youre all set.
now you have access to all of your old clients contact info and your old company cant stop you from taking them with you.
seriously though, best of luck with the job situation.
