Some knowledge on how the iPhone works

Setting it up:
Step 1: Remove your SIM card, by inserting a paper clip into the pinhole next to your SIM slot, and cut it to fit the tray that should come with the GEVEY package. Never cut into the circuitry.
Step 2: Launch Cydia and add the following repository: cydia.furiousmod.com. Then locate the "FuriousMod" package and install it. After that’s done, a "No SIM card installed" error will pop up, that’s OK. Before proceeding, make sure your phone is turned off.
Step 3: Place the GEVEY SIM on the tray, along with your own SIM on top of it. Make sure both cards are on the tray, then insert it back into your phone.
Step 4: Power your phone back on and wait around 40 seconds for your signal to be detected. Ignore any errors and don’t interact with the device until your phone picks up the signal.
Step 5: In order to get 3G, turn on Roaming Mode by going into Settings > General > Network and selecting "Data Roaming".
