In anticipation of either selling or trading in my iPhone 4S (I ordered a 5), I've "unjailbroke" it and returned it to "stock" IOS, version 6. I didn't run a lot of apps through Cydia, but I sure liked the ones I did run and though I am not a phone programming or hardware geek, I cannot for the life of me figure out why Apple doesn't allow or accommodate "official" apps that allow: Call Blocking, with a variety of ways to set it up so it performs the way you want, just as the callblock app available through Cydia does. The new "Do Not Disturb" is not call block. Toggles, so you can turn off/on cell data, sound, other controls, from the notification center instead of drilling down through apps, menus, selections. This is a really annoying "d'oh." Screen Lock changes. Silence Phone Why is getting access to this sort of thing such a big deal with an iPhone?
