Completed!! Thanks for everyone's input! I never changed my root password after jailbreaking since I didn't know how to and Terminal did not work (but now I know how to through my computer). I never had any problems until a few weeks ago at my university. Someone got into it and now my network access is cut off by my school (it was supposedly attacking other computers), and in order to get it back, I need to reset my iPhone to factory settings. Also, my battery life decreases extremely fast whenever it's connected to wifi, presumably from the malware, so I'd really like to get my phone back to the way it was before. My device is an iPhone 4. A few questions: I unlocked it last year through an IMEI unlock thing from ebay. Will my phone stay unlocked after I restore it? If I restore my iPhone to factory settings through iTunes, will it automatically be restored to iOS 6.1? It is currently 5.0.1. If it doesn't, should I restore anyways, then update, then jailbreak? I already backed up my phone in iTunes. The malware shouldn't stick with the backup, right? I apologize if any of my questions were answered in the past. I'd just either 1) like clarification/a more recent answer or 2) did not see them.
