I have iphone 4S (jailbroken), currently running iOS 5.1.1. I'm planning on updating my iOS to 7.0.4 (the most current one), but I'm having few doubts. What are the pros and cons for upgrading it?
From what I read so far off the net, I heard ios 7 will MAJORLY slow down the phone AND use up lots of battery. I don't particularly have problem with using up the battery, unless it consumes x3 or so. But slowing down is bad.
Anyways, like I said before, what are the pros and cons? In addition,
1. What will happen to my apps that I installed? (non-free apps that I downloaded from installous, app cake, etc)
2. What will happen to my apps that I downloaded off Cydia? (iFile, Blutrol, etc)
3. I heard numerous rumors about how sometimes, the update for iOS will fail, and I'll have to literally erase EVERYTHING, or worse, buy a new phone. Is this actually true?
I know it is lots of questions, but if someone can help me with these questions, or maybe guide me to the answer, I would greatly appreciate it.
