iOS 7.0.4 – is it worth updating?
The answer depends on whether you are an active FaceTime user.
According to changelog, the update only fixes FaceTime calls for some users. So consider upgrading only if you regularly use FaceTime.
Otherwise, it’s not really worth to spend time applying the update: you need to free up some space on your device to apply it wirelessly. You would need to do the same if you decide to apply it using iTunes.
If you are still on iOS 6 with jailbreak, and considering to update – just don’t (if you want to keep your jailbreak). There is no jailbreak available for iOS 7.
The iOS 7 itself is unstable till date, and if you are used to nice design, prepare for some shocking discoveries – after you get iOS7, you might want to go back immediately (but you won’t be able to).
Let’s cross our fingers and wait for Apple to release something worthy next time!
