Well guys, I finally conquered my fear and jailbroke last night. I could not be happier. Dont know how I did without Intelliscreen for so long. Since I am new at this, I need your help.

1. Does everything backup in itunes like when it wasnt JB'en?
2. When the next update comes out (2.2), what do I need to do?
3. What is installer?
4. I downloaded winterboard, but I really want like 3D icons, but Winterboard does not come with icons? I am looking at this right?

I apologize if this is not the forum for these questions.
Thanks in advance.
