here is the method to unlock your iPhone 4 using Gevey Sim on iOS 5 or 5.O.1
all you need to do is to Update using a custom made Firmware so that you do not update your Baseband.
for this you require…

Download Redsn0w here for WINDOWS & MAC.
2-iOS 5.0.1 Firmware which can be downloaded from iTunes this is for iphone 4 GSM,
3-iPhone 4 (ofcourse)
4-a little knowledge of DFU mode and Jailbreaking (read other posts if you don’t know this)
5- A GEVEY Sim for unlocking
Caution- this will work only on baseband 04.10.01 & lower only and not on the updated base bands
STeps to follow
1- open Redsn0w and then go to EXTRAS and select>> custom IPSW.
store your downloaded ios 5.0.1 on the desktop so that you located it easily.
2- now again open Redsn0w and go to Extras>> then click Pwned DFU and follow the steps.
3- now open iTunes and manually restore using Shift+Restore or Optio+restore using the custom made IPSW.
4-once your iphone is restored, open Redsn0w again and this time click Jailbreak and follow the steps, its EASY, install Cydia by the way… you will need it later on.
5- Once the jailbreak process is over and your phone starts, Open Cydia>>Go to Manage>>Sources>> then add this source manually
