If I had to guess, I'd say the people doing the complaining and the people doing the swearing are two different groups of people
That said I've got maybe 150 MB free, on a jailbroken iPhone 5 running 6.1.2. Not even close to worth the trouble, lol.
If a jailbroken phone is important to you then none of this matters until someone comes out with an iOS 8 jailbreak. Which makes me wonder why you'd even bother to post in this thread.
