I cannot wait to jailbreak my Verizon iPhone, but before I do I would like to know its status. Questions regarding the greenpois0n 4.2.6 jailbreak: 1) Is the greenpois0n 4.2.6 untethered jailbreak stable? 2) Does jailbreaking effect the battery life of the iPhone? 3) What about the overall speed? 4) Which applications in Cydia suck up a lot of battery and should be avoided? 5) When jailbreaking will I lose all of my music, applications, contacts, and other data from the iPhone? 6) Will I still be able to sync my phone with iTunes? Thanks!
