I've been holding out for years cause I hated the new look of IOS 7 and I've held out as long as I could and now a shit ton of apps can no longer be updated and newer apps cant be downloaded unless I'm on IOS 7 or later. So I have a few questions to ask before I decide to do anything here. 1. Is there anyway I can roll back to my current firmware if I decide I dont like it? 2. I have a ton of Jailbreak crap on my phone, anyway to back all that up so I dont have to reinstall and reconfigure everything once I'm on a newer firmware? 3. Whats the latest most exploitable firmware for jailbreaking? P.S. My only motivation for finally wanting to update after all these years is because of Miitomo, *sigh* Nintendo.
