Want to unlock iPhone 4 on iOS 5 with Gevey ULTRA SIM UNTETHERED ?
Well, if you are going to update your iPhone 4 to stock iOS 5 firmware you will render your unlock and your Gevey ULTRA SIM useless. To unlock your iPhone 4 on iOS 5 with Gevey ULTRA SIM you MUST update your iPhone 4 to Custom Firmware which preserves the unlockable basebands that are compatible with Gevey ULTRA SIM. Also you should do this procedure from FW 4.3.3 or 4.3.5 or lower.
Or from any FW that has the supported Baseband for Gevey Sim Ultra.

Note this is a non-JB unlock, if you JB at this point it will be a tethered
 JB.

Here is the basic run down of the procedure:
You have to restore iPhone 4 with a custom iOS 5 ipsw that has an unlock-able baseband (BB)
Redsn0w 0.9.9b5 (or above) is the program used to create your custom ispw that has no baseband upgrade.
Then unlock iPhone 4 on iOS 5 with Gevey UTLRA SIM. MANUAL MODE.

Required Downloads and things:
Download Redsn0w 0.9.9b5 for Mac / Windows (Coming soon) Download
Download iOS 5.0 ipsw for iPhone 4 Download
Download iTunes 10.5 for Windows and Mac Download
AT&T or Original Carrier SIM to Activate
T-mobile or non Supported SIM that you want to use

How to update iPhone 4 to iOS 5 without updating Baseband - Redsn0w 0.9.95 :

Step 1: Connect your iDevice with your PC via USB and open Redns0w you just downloaded above.

Step 2: Start Redsn0w, press on "Extras" > "Custom IPSW" and then point Redns0w to iOS 5 ipsw firmware that you downloaded above.





Now Redsn0w will start cooking your custom iOS 5 ipsw firmware


Step 3: Click on "Pwned DFU"



Step 4: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”. (It is advisable to have a AT&T or orig Carrier locked sim already inserted at this point)



At this stage you will be presented with a screen where you will be guided on how to enter DFU mode. Quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.

Step 5: Open iTunes 10.5 then Restore your iPhone 4 to the Custom iOS 5 ipsw (the file name begins with NO_BB).

Step 6: Once your device is up have it activate with the AT&T or Locked Carrier sim if needed

Congratulations, Now you can unlock iPhone 4 on iOS 5 with Gevey ULTRA Sim:

-Turn Phone Off

-Insert Gevey ULTRA sim with your Carriers Sim into your phone

-Turn your phone on

-Wait until it shows “no service”

-Go into "settings" > "Phone" > "Sim Application" Below SIM PIN
Press on English or Any Language that you can read
