Sorry for the film reference in the title, couldn't resist ;-)
Anyway, I've a iPhone4, it's kinda mission critical, in that I can't really afford (time or financially) for it to be out of order. I always said I would JB it, but... Well, you know how it is.
When Lr and GP broke i read lots of stories about this and that not working on the iPhone4, my question is, is all this sorted out now? Is JBing a 4 just as reliable and problem free as JBing the 3g ended up?
It is your choice whether to jailbreak or not. One thing you have to be aware of . After jailbreaking, if you ever want an update and jailbroken again, you will need to restore , rejailbreak and install your stuffs back as to having no jailbreak and just hit restore every time when there is an update.
Iphone 4 can be jailbroken safely and always install paid apps either from Apple or from Cydia, then you won't have much issues on the phone.
