It's pretty much as reliable as the sun: a new iPhone OS update generally leads to at least a handful of issues. But iPhone OS 3.1, which was made available on September 9th, seems worse than most. We've seen tip after tip pour in, and we've watched Apple's support forums grow increasingly ugly with irate iPhone users dealing with horrid battery life, random shut downs and the occasional screen freeze. A few of our own have also experienced some of these quirks, though others have escaped without a scratch. So, we're putting it to you all -- has the latest iPhone update borked your handset? If so, in what way?
