I've been increasingly interested in the notion of jailbreaking my 3gs, however I'm having trouble looking up basic information related to doing it. I could not find any sort of FAQ, so please link one if I have missed it. I just have a few questions before I decide to actually jailbreak my phone. 1.) I bought applecare for my iphone. What will happen if it's jailbroken? Was it a waste of money, or if I need it to be looked at can I simply restore it back to it's original firmware (not jailbroken) without having the apple people ever know it was jailbroken? 2.) All of my phone numbers, and apps I purchased legitimately... Will they be lost when I jailbreak the phone? 3.) What is the most common/normal way to jailbreak the 3gs (is the 'Pwnage Guide' sticky up-to-date and what everyone is using currently? 4.) How much trouble is it to jailbreak, and is it common to endure problems/bugs (overheating, no service, low battery life)?
