    Hi all

    My friend has an AT&T 3GS with baseband 05.16.05. His provider is Telus in Canada and I've been unable to get the Telus SIM card to work in the phone, after using a number of different unlocks. We used GreenPoison, redsn0w and finally updated to 5.0.1 to see if redsn0w would unlock it then. Cydia had a white icon and I just now searched that there's a way to fix it. However I don't think this will resolve the SIM issue because of the baseband.

    I'm not sure if I need to update the BB to the iPad 06.15.00 or leave it?

    If I do that, do I need to downgrade to 4.3.3 or is there something on Cydia that will unlock a 5.0.1 iPhone 3GS in Canada?

    And if I do THAT, I didn't see that you needed SHSH blobs saved to revert so is there a workaround for that?

    For the love of science, show me the answers!! Thanks :D

    tl;dr how do i unlock a iphone 3GS 5.0.1 with a BB 05.16.05 in Canada for Telus?

    Fixed ;)

    -revert from 5.0.1 to 4.1 using an older version of itunes (google it)
    -if you get errors just put it into PWNED DFU mode (step i found)
    -you'll get that 1510 error or something (that's good)
    -then DL tinyumbrella, click your phone, then exit recovery
    -use redsn0w to install just cydia (NOT the ipad baseband at the same time)
    -let it go through, your phone turns on
    -then turn your phone off, run redsn0w again
    -uncheck cydia, check ipad baseband
