I've been having problems while using cards in both the SD and miniSD slots at the same time. It freaks my 6515 out and won't let it sync to ActiveSync. It took me a 14 hours of massive frustration to narrow it down to the simultaneous use of the SD + miniSD cards!
I had to do a ful hard reset and only use the miniSD card and reinstall ALL of my programs all over again, delete the ActiveSync partnership and then resync to get things somewhere near normal.
I'm weary of using both the card slots at the same time again. Has anyone else experienced this or have heard of this issue?
BTW, I have a 1GB SanDisk SD card (Storage2) and a Kingston 1GB miniSD card (Storage).
