First iPhone, first JailBreak questions. Warning: I know some to most of these questions can be answered by surfing the web but I wanted updated answers as the newer JailBreak may lead to different results. Device: iPhone 4 iOS 4.0.1 Questions: I have AppleCare 2 years if something happens can I do a DFU and have no traces of the jailbreak with the new jailbreak. Have their been any statistics of bricking the iPhone with the old jailbreaks or the new jailbreaks. What are the chances my phone will brick and if it does can I restore it in anyway. (If the PSP bricked during a custom firmware install their was a Pandora Battery to fix it) Will my current movies, music, apps, ringtones, settings remain. If I do a restore of a previous backup on iTunes will I keep the jailbreak firmware or will it revert to iOS 4.0.1 or will it brick. Can I still install apps from the App Store / iTunes Store? What if I want to upgrade my phone from a jailbreak firmware to a new official iPhone firmware such as iOS 4.2. How would I go about doing this? Does Apple have a history/plan to, due to the new laws, to brick phones purposely OTA or through iTunes if they are jailbroken. (Sony did this with the PSP) Can I create backups of my Jailbroken firmware? Is any part of this still illegal? (Other than downloading illegal apps like Emulators) This one might sound stupid. Can I get it "professionally" jail broken (meaning go to one of those small self-made wireless stores that jailbreak it for you) and do they usually cover the phone if they brick it. I am a Apple Developer, how does this affect me and my membership and my ability to do on-Device debugging/testing. Thanks for any help.
