Hello, so I currently have an iP4 with 4.1 installed. Yes, I know 4.1JB is not yet released. But this is my first ever iphone and I'm very tempted to jailbreak it once the JB is released. I know NOTHING about jailbreaking. Is it relatively easy to customize your themes and lock screen, etc? What are the must have Cydia apps? Would the regular Apple apps I already have installed still work? I dont know, I'm just afraid since I've never done this and would rather not break my phone due to my incompetence with JB. My main reason to JB is to have custom text sounds (soooo fed up with having the same tone as other iphone users) and to customize the themes and lock screen. So any advice or tutorials for this noob? Thanks guys!
