    Thanks to all the active members out here for all their support over the years. I really appreciate it.

    I bought an iPhone 4 on 4.0.2 and baseband 01.59.00. It seems that the new Limera1n can jailbreak 4.0.2 as well. I have tiny umbrella and have saved my shsh using that tool on my mac. However, since I have never used Umbrella to downgrade or for anything else, I need help on how to upgrade my iPhone 4 to 4.1 while preserving the baseband so I can jailbreak using limera1n and then use ultrasn0w to unlock it.

    Is this even possible? If so, can someone please guide me on how to go about unlocking my iPhone?

    I am sure this will be useful for all the people who have been waiting patiently on v4.0.2 for an unlock.

    Thanks in advance.

    Tiny umbrella comes with a readme file. It's all there.
