1) Now the the official 3.0 has been released, is the jailbreak tethered or untethered? 1a) Also, QuickFreedom doesnt support 3.0 jb? What software do you use? 2) Some Cydia apps won't work in 3.0? Is there a list, and they will eventually be supported, correct? 3) Do I have to upgrade to iTunes 8.2? 4) Right now, is it better to keep 2.2.1jb or upgrade to 3.0?
