So my iPhone sometimes crashes or freezes. Went to the Genius Bar and they were able to see the errors. Was told to wipe and reinstall all my stuff without restoring from a backup (they said the errors will just get transferred into the backup and onto the new install). What I want to know is how can I do this without losing anything? I have so many important things on my phone and cannot afford to lose any of it...I'm honestly very stressed out about this!! Really sorry if this is a dumb question, I'm a real noob!!! Thanks for all your help!!!
