I just ran a complete: back up / restore like new / restore backup On my iPad rMini. I was having issues with the mail app freezing on occasion. To get past the problem I would close out the app and stop it running in the background and open it up again. It would then work. Rather than killing my Sunday tomorrow with a genius bar appointment to run diagnostics, I wiped it to see if that would help. Time will tell. The upside is that I picked up over 6gb in useable space-going from 6.3 gb available to having 13.5 gb now. I guess it's good to clean house now and again. Hope I fixed my issue.
