I'm getting an iPhone (finally) in a few weeks and am weighing the pros and cons of jailbreaking. While I like iOS better than Android (and iOS 7 is really the clincher for me) I'm jealous of Android apps like Tasker, Llama, and others that adjust settings based on context (especially location). There are a few iOS apps in Cydia that do similar things, and I like the thought of added customizability that jailbreaking provides. However, I don't know how much I'd actually use some of those features. To both those who have and haven't jailbreaked (jailbroken?) your iPhone, what made your decision? Are there negatives to doing so?
