Ok, lets say that i have an iphone 4 with ios 4.1 jailbroken with a 01.59.00 baseband preserved with tiny umbrella and saved shsh with tiny umbrella as well My first question is, if i were to restore my phone like it has never been jailbroken, would i have to restore it with the stock 4.1 update? If so that would lose the 01.59 baseband, correct? This is just a situation i was thinking about. Any input is appreciated My second question is regarding unlocking. In all essence, if you unlock your phone, all you have to do is plug in a sim card for that certain carrier (tmobile, o2, at&t) and it will work on that carrier?
