Hey what's up everyone. I'm new to the whole jailbreaking scene and still trying to figure all this out. I have a 3g with software 2.0.2 installed. I was wondering two things right now: 1) if I jailbreak my phone does that mean I no longer update it through iTunes? 2) if I jailbreak my phone will I lose all of my contacts and programs that I'm already payed for and download through iTunes?
