    You updated the phone and removed the unlock. You are out of luck unless you can downgrade the phone and reunlock the phone again. It looks like you will be phone less until an unlock for 4.1 or 4.2 comes out.

    Nothing you can do now but wait for a new unlock and jb.
    You gotta be alot more careful with a jb and unlocked iPhone.

    This is a real problem that hurts Apple's reputation and sales.

    If you read it. It states it will allow you to update your phone to 4.1 using windows and without updating the baseband. You've already updated the baseband when you updated to 4.1 in iTunes so there is NO unlock that will work for you right now. You have to wait unti the dev team releases an unlock for the new baseband. No one knows when this will happen.

    You can follow the official dev team blog by going to Blog.iPhone-dev.org. When it released it will be announced here first.

    Erase content and settings.

    My current OS is 4.1. that wht i mistakenly did. now my phone is locked and wid unsupported SIM. nothing i can do. i'm from bangladesh. my prevous OS is 4.0.2 and dat was unlocked and jailbroken.
    if i perform 'erase content and settings' on iphone what will happen then? will it delete my current firmware, baseband? after deleting that may i able to restore to 4.0.2 or any other iOS? what will happen in os and base band. will i be able to jailbreak older os?
    Plz some one let me know.

    thank you.

    You cant go back and undo it now bro.
    With the 3GS is very tricky and you cannot downgrade the baseband to unlock ever once updated.
    All you can do is wait, you're pretty much stuck now.
    You might also need an official simcard to activate it or a phonebook sim.
