Gevey cards are currently the only method to unlock an iPhone 4 terminal whose baseband is greater than the value 01.59. These cards must be inserted together with the normal SIM in our terminal and by calling the number 112 it decodes any baseband available for the iPhone 4 terminal. Many chose not to use these cards precisely because they have to call 112, but the card manufacturers managed to make a method that eliminates the need to call the 112 service. By installing a tweak from Cydia called FuriousMod and buying the Gevey Ultra card you will be able to avoid calling the number 112 but you will be able to decode the terminal without problems.
The new Gevey Ultra cards are available on the manufacturer's website at the price of $28, the same as for the previous versions. Any version of iOS can be installed on your terminal, including iOS 5 for which baseband Gevey still decodes. In the clip above we have a demonstration of how the cards work, but for now I can't tell you what process that tweak performs and how the decoding is done. The source from which you need to install FuriousMod is http://cydia.furiousMod.com.
