Thanks, I appreciate it. The biggest hurdle for me is that there is so much information out there and a lot of it seems to conflict. For instance, what the previous poster just wrote (post #90). That tells me I should just give up now. Then you give me this link, which leads to this, saying the exact opposite, but not mentioning newer bootroms. It seems overly difficult to find one place that addresses every concern. That's why I've always stuck to reading dev-team's blog, because it addresses every level of iphone in a coherent manner.
Advice, try to avoid listening to poster on post #90
