I have a couple of questions. First, I understand that if I want an iPhone that is unlocked, but not jailbroken, I have to jailbreak it, unlock it, then de-jailbreak it. Is this correct? After this, can I upgrade it without locking it, or does upgrading lock it again? Second, I have two iPhones 4, the first one is 4.3.3 baseband 4.10.01, and the second one is 4.0.2 baseband 1.59.00. From the info on this link: http://www.iphonedownloadblog.com/2011/05/08/iphone-4-3-3-unlock-everything-there-is-to-know/ The first one cannot be unlocked YET And from the info on this link: http://www.iphonedownloadblog.com/unlock/ The second cannot be unlocked, and likely never will be, as it is an old version nobody is working on (the only such version, lucky me). All of this correct? ...Unless buying a Gevey or a Rebel, of course.
