There are loads of sites similar to this all over the net. All they are selling is the same solutions you can get for free right here on this forum.
DO NOT BUY!!!
The only iPhone unlocking worth paying for is the permanent unlock solutions which are available for a limited No of networks around the world. If you are waiting for a solution for 4.1 then you are better off waiting rather than paying one of these sites who will take your money & tell you the same.
If you want any info about permanent unlock solutions available send me a PM
Thanks
