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
