Ok so I am completely new to this stuff, I've had an iPhone quite a while but I got it jailbroken so I never really wanted to tamper around with it but, I've had the 3G since launch so the firmware is pretty outdated. It's jailbroken but how on earth do I update it and keep it jailbroken and unlocked? It's been running really slow lately and hopefully this update will fix it! I don't really care if I lose my data, but just wondering if I'll be able to at least keep my contacts and photos? I did see the tutorials but they just confused me even more, tons of different ones and just saw many things that were confusing, please any help would be appreciated!
