So I kind of screwed up my iPhone 5 by messing around with the TelephonyUI Framework on iFile, and now most of the buttons on my phone have disappeared. (accept a call, decline a call.) I am a registered developer, and I already have iOS 7 beta on my iPads. I am considering upgrading my iPhone 5 jailbroken on iOS 6.1.2 to beta 5. I just have one important question. If I upgrade to a beta from a jailbroken iPhone, will anything go wrong? What I mean by that is things like damaged apps and the iOS itself. Any advice?
