I'm using the latest ios 7 beta. I know there are many threads on this but it still doesn't clear things up for me. Instead of just backing up then upgrading, people say I should set up as new or reset to factory settings, etc. Doesn't that mean me starting at square one and having to download everything again while losing my data? I only use iTunes through the PC as I dislike iCloud. Would it really be harmful to just handle it as any other update? Starting fresh is not an option for me.. Thanks in advance.
