    Do you mean it has not worked? If it worked, why do you need yellowsnow?

    What do you need to fix? What model of phone, what firmware, what computer / OS are you using?

    I am not surprised, though I say it is more of a lucky occurance than anything else.

    My iPhone 3G on 2.2.1 could run on a softbank (japanese carrier) SIM card even though it is only officially unlocked to my own carrier back home. Even the agent from my carrier can't explain why it can work, except to offer me advice that I am apparently not an isolated case.
