In my backup and reset menu I have two boxes titled 'Backup my data' and 'automatic restore' -both are ticked. Basically im concerned that id lose my contacts, apps and personal data. I have an external sd card that has just music on it and dropbox puts pics there too. Should they USUALLY be ok with these boxes ticked? I know I can use an independent app so dont tell me that! And ill take my sd card out obviously.
