    Default iPhone 4 Firmware upgrade with some requirement
    I apologize if this question has been answered before. I spent a bit of time searching the forum without finding anything.

    I have an iPhone 4 that is currently running iOS 5.1.1 with an untethered jailbreak. I have used preserve baseband so it is on 04.10.01. I also have Gmail exchange push.

    I believe I have the SHSH blob 6.1.2 saved by Cydia and 6.1.0 saved by tinyumbrella.

    Is it possible for me to upgrade to iOS 6, untether jailbreak it, preserve baseband, and keep the Gmail Exchange push? Or do I have to lose something in the process? Thanks for your help.

    Install iFaith to your PC and chech the saved blobs. Frankly, I am not sure that they are OK.
    If yes, you can do what you are asking, if not, than the only option you have is 6.1.3 with tethered JB
    You are also using Gevey, right?

    Following bbrks' instruction, I was able to upgrade with baseband preserved and Gmail push preserved. Thank you so much for pointing to iFaith!
