To begin, I'm not asking this question for myself. I'm familiar with how to jailbreak an iPhone and have done so many times. It's my Dad that needs some help. He's in his late 50's, is relatively computer capable compared to most of his generation, and has decided to jailbreak his iPhone 3G (already upgraded to OS4)--having finally accepted that jailbreaking isn't equivalent to theft. iTunes 9.2 running on Windows. Normally I would just give him instructions myself, but I'm in the panicked throws of packing for a 6 week long trip to England that begins tomorrow. I've searched a little online for guides that I can link him to but just can't decide which one is the most through and, of equal importance, easy to understand. If you have a suggestion, please post it. Also, if you know of any good Cydia guides or explanations...post them too.
