    Hi there. I got an Iphone 4 from AT&T but its lokced. I need to buy a turbo SIM to unlock it once Apple has cancelled the regular unlocking by mobile companies in Brazil. Let me know how to check the firmware version on it because I can only do emergency calls. I've tried the same trick from the old Iphone like *#3001...etc... but I doesn't work. Let me know if I can find out the firmware because I need to know which turbo SIM works with my Iphone.
    Thank you all!

    Ricardo

    don't know if it will work but download tiny umbrella and the program will show you the firmware.
