Yesterday, iH8sn0w released patched PwnageTool Bundles to jailbreak iPhone 4, iPhone 3GS (both Old and new Bootroms), iPod touch 4G / 3G and iPad. These iOS 4.3 GM bundle for PwnageTool preserve the iPhone 4 BaseBand.
If you’re iPhone 4 is already unlocked on baseband 01.59.00, you can safely restore your device to a custom 4.3 pre-jailbroken IPSW and retain current baseband and unlock, instead updated upgrading to BB 04.10.01.

Step 4: Select ‘Edit’ and then select ‘Add’. Now enter a URL source. Type ‘repo666.ultrasn0w.com‘ and select on ‘Add Source’. Once Cydia has added the source click on ‘Return to Cydia’ button.
