hi, like 2 or 3 days ago i jailbroke my iphone and unlocked it too, i had to restore it, then rejailbreak it. today, i was hearing somethings bad about jailbreaking that apple has said such as battery life drains faster, performance is slow, and even viruses. so today i restored it, first i restored it just by plugging it in and hitting restore, then after it was restored, i erased content and settings, then i put it into dfu mode, restored it, then i erased content and settings again, then put it into recovery mode and restored it. now has this completely gotten rid of the jailbreak? and also, if i do a software update after it has been restored after a jb, is it possible to still get bricked? thanks and i look forward to reading your answers!
