What is the best/most popular website that will explain how to jailbreak my iphone 3G? Also, what is the most popular/best website for items & themes I can download for my jailbroken phone. If I do not like it, all i need to do is hook my iPhone up to my laptop and click restore on i tunes? After I do that how would I get everything back that I have on it now after I back it up? Would I just sync it with my iPhone? Also, what are the negative & positive things of jailbreaking an iPhone now? is there an official site that will tell me what the most up to date version of jailbreak is out? also, how do you know what actual version of the iPhone software you are using? i.e., if I have the Jailbreak version of 2.0, how would I know what iPhone version I am using? and one more when I want to update a jailbroken iphone to the newest firmware, do I have to restore the iPhone, or how does that work? thanks.
