I'm planning on getting an iPhone, and I will probably buy it as a 1.1.4/1.1.5. Before i do anything i'm going to Jailbreak. My question is, after i get all my Apps, Summerboard Preferences, WiFi settings, Contacts, etc. Am I able to save these, restore, jailbreak, and load these again? Also, if I add contacts along the way, the computer and iPhone will sync up, but ff i add some contacts on the iPhone, and delete some as well, will it sync my Address Book to my computer and not my computer to my iPhone?
