my iphone4 is currently on baseband 1.59.00 locked and version 4.1 jailbroke by limera1n. i really dont care about not being able to unlock since im a at&t customer, but i care about the resale of my iphone4 later when the newer one comes out. is it safe to just upgrade to 4.3.1 via itunes and use redsnow to jb while upgrading my baseband to the current version? what do you think the chances are that the newest baseband version will be able to be unlocked? it helps tremendously in resale value.
