The method described below will enable you to virginize an iPhone with 1.02 firmware thus allowing you to upgrade to 1.1.1 firmware. This virginizer is to be used only by iPhones that were unlocked using the Anysim 1.0 - 1.2 or iUnlock method. Do not use this if you’ve used the iPhonesimfree method. Use at your own risk.

1. First follow this guide to jailbreak your iPhone.
2. Open Installer and update. Restart Installer and go to the Sources tab at the bottom and press “edit” and then “add”. Type in “http://rep.frenchiphone.com/” and press “Ok”. Then press “Refresh” at the top.  In Installer go to the ‘Install” tab then “All Packages”. Install Community Sources, BSD Subsystems, Open SSH and Anysim 1.1p. Exit Installer and then run Anysim 1.1p. Disregard the warning about putting in your own sim. It will unlock your iPhone regardless of what sim is installed. Now Slide To Unlock and press the big red button. Wait five minutes and your iPhone should be unlocked.
3. If you’re having issues with Youtube not working, go to the link in the first step and read all the way to the bottom to fix that issue. Enjoy.

This method patches the MeCCA.framework file enabling you to use your own custom ringtones and survives synching thru iTunes unlike other methods.

Step 1. Patch the MeCCA.framework

Download the patched MeCCA file here.

Place the extracted file into /System/Library/Frameworks/MeCCA.framework replacing the previous file.

Reboot your iPhone.

Step 2. Create your ringtones

Use iTunes to convert sound file to AAC (.m4a), then rename the converted file to:

ringtone_name.m4r

Notice: there must be a space before .m4r, so, a ringtone named ringtone.m4a should be renamed to ringtone .m4r.

Upload the renamed ringtone file to /Library/Ringtones, it appears in Settings->Sounds->Ringtones list immediately.
