I will not get an iPhone 5, but if I would, then I probably would not see enough reason to do it. I did not with the oid one. Everything I needed was built right into it and done good. Otherwise it is with some Android phones, I own one now, and had to root it to use the Apple Bluetooth Keyboard and even had to install a new keyboard, because the original Samsung keyboard on the Ace is so bad. It is funny, that the "closed" iPhone would not be reason enough for me to break free, but the "almost open" Android is.
I'm certainly not... Not just because I'm against it or because it's illegal, but honestly, I see no reason to do it. Unless you would like to download a massive numbers of paid apps, a normal use of an iOS device, it's completely sustainable for your wallet!
Like Steve Jobs said: "I think people are really disposed to pay for content, there's just no easy way to do it!"
Well, now it is! :D
I am not jailbreaking my iPhone 5 since I have been using iOS devices over 2 years and I got most of my apps for free. I use appadvice and it tells me every app that gone free for every day. For some games like infinity blade, I buy it. By jailbreaking, I can get awesome additional features like android, but I don't want to make fragmentation to OS and I want to update the latest iOS version on the day one.
I would like to jailbreak the phone to add spyware - as a parent, it's wise to keep track of what your teen might be doing on the phone - and apple as no resource for this. I've yet to do it because it voids the warranty. Have you had any problems with this and was it hard to do?
