    I have an unlocked iphone 3gs using it on Tmobile network and would like to update NOT to the very latest software which I think is like 4.3.5 or someting around those lines. How can I update my iphone without loosing the unlock portion of it. I have cydia on it. All I ask is if someone can guide me thru it so I can do it, Im not too techy but given the correct instructions I can follow them to the letter. Thank you all this is my first ever post on here, hope someone would be kind enough to help, please. Thank you so very much.

    Did you save any of your SHSH blobs? Without them you will only be able to update to the current iOS version which is 4.3.5.

    Sorry I have no idea what SHSH are. I bought the phone already unlocked to 4.0 with Modem Firmware 05.13.04

    This link explains what SHSH blobs are: http://forums.tipb.com/jailbreak-unl...jailbreak.html

    You should be able to check what blobs you have saved by opening Cydia. If you look at the top it should say there which ones you have saved.

    I opened up Cydia and on the very top it reads: SHSH: iOS 4.1, 4.2.1+, 4.3, 4.3.5
    so now what do I need to do?

    4.3.3 is untethered just run tinyumbrella and shift click restore to 4.3.3 file you will have downloaded somewhere

    Download the 4.3.3 firmware and place it on your desktop
    Next download tinyumbrella and run. Open it up and click StartTserver
    Now open iTunes and hold shift and click restore. Now a window should pop up and just click on the 4.3.3 file you downloaded and click open.
    There you go if you run into any other problems please post here

    One small thing: I don't think you can actually use 4.3.3 if your SHSH only lists 4.3, right? If you're going to do the Shift/Restore method make sure you're using a firmware for which you have the SHSH saved.
