This is a more broad question than just going to iOS7.
Is there a reason to NOT just upgrade and to do a fresh wipe and install of iOS?
Does the backup retain "bugs" and "errors"?
I think I'd read in the past it does keep all the "character" acquired such as errors that stay hidden from the user (that apple techs access at the store)
I'm not looking for "My phone SEEMED better after..." but actually proof one way or another on the matter.
