Hi, I'm about to jailbreak my iPhone 4s running 5.1.1 using the latest Absinthe. The guide says that I should reset all settings and data before jailbreaking and then restore afterwards. Is it really necessary to do this? I have 25GB data on there and don't really want to have to restore everything if I can avoid it. Can I not just jailbreak it as it is or will this cause problems? Thanks for any help. Apologies if this has been answered before.
