how can i restore my iphone 3gs w/o upgrading
i want to restore my iphone 3gs 3.1.2 so i can jailbreak/unlock it and then sell it. but i don't want to upgrade to 3.1.3 since it would prevent me from jailbreaking it. is there any way to restore my iphone without upgrading to the latest software?
btw if this makes any difference, i do have SHSHs on file for 3.1, 3.1.2, and 3.1.3
