Actually, there is one negative side of this Gevey sim. It won't unlock iPhones that have been put to the ''Black List'' (It means that it won't work with any carriers)
Can anyone comment on this?
I have an locked AT&T iphone 4S iOS 5.1 and am going to buy the Gevey Ultra ver.1.6 from applenberry soon. I need to use the phone outside of the US using other carriers.
Please advise. Thank you.
