Yes, it is possible to jailbreak and unlock an iPhone 3GS on iOS 6.1. To jailbreak, you can use tools like Redsn0w or p0sixspwn. For the unlock, your device needs to have a compatible baseband, specifically version 05.13.04, to work with ultrasn0w. If your baseband is a different version, you may need to use Redsn0w to install and then downgrade the iPad baseband (06.15.00) to reach the 05.13.04 version. Make sure to back up your device before attempting these procedures and check if your bootrom version requires specific steps.
