Hello, Sorry for another jailbreak thread but I had a few questions that I couldn't seem to locate an exact answer - nor did I want to hi-jack anyone else's thread. I'll get on to the questions.. 1. Should I go ahead and jailbreak 3.0 or wait until 3.1 jailbreak is available? 2. What exactly does Cydia do? 3. Can you also download iTunes Apps from the AppStore along with jailbreak applications? 4. If you currently have 3.0 OS installed, is there anyway to keep from losing your music and apps when jailbreaking? Sorry if this has been answered a million times (which I'm sure has), but I am completely new to this scene and would like to get better informed before I try jailbreaking. Thanks in advanced!
