This is the first time I'll be jailbreaking an iPhone, so want to get some questions clarified: 1. Do I need to backup all the contacts, notes and photos on the iPhone before jailbreaking 2. Will I be able to sync music from iTunes on a jailbroken iPhone 3. Will already installed apps continue to run and can I install apps from iTunes (which may not be available on Cydia, Also is there a good way to browse Cydia appstore to see what apps are available?) 4. I'm going to follow the steps on iclarified, do I need to backup anything else for future restore, I read somewhere about saving SHSH blobs and saving the baseband.
