So I'm still on iOS6 because I'm weary of iOS7 on my iPhone 4. The updated downloaded as expected to my phone last week, swelling my "Other" section in iTunes to about 4.5 gigs (up from 2.25gb). I experienced this last year with iOS6 as well so I assumed the space would be gone until I inevitably was forced to restore and update. I plugged my phone into my computer today and got the popup saying "New download available - iOS 7.0.2." I checked the box that said "Don't ask me again" and then clicked "cancel." My phone then synced, and Viola! My space is back to normal. I still have a notification for my "Settings" icon on my phone, but I've gained back the space I lost with the auto-download. Does this work for anyone else that has not yet upgraded? I'm curious to know if this is a fluke or if Apple changed their policy. Chime in!
