They are offering to unlock iphone 3Gs version 4 but they don't have the software available. They are using the files from the DevTeam for lucrative purposes. The page looks original so you think they are real and honest but they don't...Please do not take the risk to lose your money. I just open a paypal dispute so I should receive my money back. I saw another comments from other people that they use Daypal and they can not receive the money back. I fortunate to use Paypal because am covered for this fake things.
I know that everybody that has a 3GS with bootloader 6.4 and version 4 wanted to unlock their phone right now but you guys need to wait (I learned the hard way) until DevTeam have the unlock available so please be patient.
