Hello, I was just wondering if i am jailbroken with ios 7.0.4, will it be possible to jailbreak to ios 8 when it comes without losing anything on my phone, and if so, how to do it? If i would lose data, I could just backup my phone first, I would hope? Btw i have a jailbroken iphone 5S on ios 7.0.4. Thanks in advance!
