FerTouchStyle… I also have iPhone 4 with BB 4.10.01 and able to unlock with Gevey Ultra in iOS 5.0.1. After upgrading to iOS 5.0.1 with a Sn0wbreeze preserved baseband custom firmware (no tethered jailbreak). Here are the step that I unlock with Gevey Ultra:
Note: The important thing is that Cellular Data and Data Roaming MUST be ON. Sometimes, after a power + home reboot or power + red slider reboot, Data Roaming is turned off by default. It must be turned on before attempting the step below.

1. Power + home reboot
2. Wait for Gevey welcome screen (if it doesn’t pop up, go to Setting->Phone->SIM Application then click on English)
3. Click Accept on the Gevey welcome message
4. Wait for No Service then count 4 seconds
5. Dial 112 then end call after two seconds
6. Turn ON airplane mode
7. Wait for “No SIM Installed” message then click on OK (around 30-90 seconds)
8. Turn OFF airplane mode
9. Two messages will popup, click OK on the last one
10. Cellular service will come on after a couple of minutes
