running 4.0 unlocked/jailbroken, want to upgrade ios and keep unlocked
I have a jailbroken and unlocked iphone 3gs running ios 4.0. Many new apps not compatible with older ios. I need to upgrade ios and then unlock...don't really care about jailbreaking again but MUST be unlocked so I think I need to jailbreak as well. I do have cydia on it currently. What can I do?
Es esta una buena pregunta?
