End game: is it possible to keep iOS 7 off my iPhone 4?
I have a iPhone 4 on which I have quite purposefully not yet installed iOS7, though it is sitting on my phone because Apple pushed it to me (nearly frying my phone, and requiring tons of work to free up space to stop the literal meltdown). I have heard too many horror stories from folks with 4's trying to use iOS 7 software that so outguns the hardware. But I am receiving a new 5s next week!! Can I back up my 4 into iTunes without it installing iOS 7 by itself? If so, is there any way to prevent the 4 from installing iOS7 after I erase my phone to sell it? I'm thinking it's actually worth more un-updated! Thanks for your help!
iPhone 4, iOS 7, 16gb
