How To Unlock Your iPhone 4 On 4.3.5

The GEVEY Ultra SIM allows you to unlock your GSM iPhone 4 and use it on any GSM carrier – it’s extremely easy! This method compatible with iOS 4 – iOS 4.3.5 and iOS 5 b1 (it will not work on iOS 5 b2 or higher) and here’s how to do it on your Jailbroken iPhone:

Step 1: Cut your SIM card to fit the tray, the GEVEY package should come with a SIM cutter – remember, DON’T cut into the circuitry!

Step 2: Open Cydia and add the following source: cydia.furiousmod.com. Install the “FuriousMod” from that source. After its finished installing, you’ll get a “No SIM card installed” error – it’s fine, just power off your iPhone.

Step 3: Open the SIM tray (with a paperclip) if it isn’t open already and then place the GEVEY SIM in the tray, along with your carrier’s SIM on TOP of the GEVEY SIM. Once BOTH SIMS are in the tray, insert it back into your iPhone.

Step 4: Turn your phone back on and wait around 40 seconds for your signal to register – make sure you IGNOREany errors and don’t even interact with your iPhone until it picks up a signal.

Step 5: You’ll now have service – but, in order to get 3G, you’ll need to turn on Roaming Mode and you can do that by going to Settings -> General -> Network then select “Data Roaming”.

That’s it, you are officially unlocked! You can pick up your GEVEY Ultra SIM here.

Here’s a demo video on how to properly use the GEVEY SIM (it will still work even though the video doesn’t say 4.3.5):
