My dear brothers don't waste your time. This was factory unlocked set. The expersts can determine in even one look. there is no cydia and this is new boot rom.

Yes ,But remember,this PwnageTool only works on previously jailbroken 3GS devices with the old bootrom. If you have an iPhone 3GS with the NEW BOOTROM this is NOT supported by PwnageTool 4.0
