I have been doing carrier unlock for the Samsung Galaxy S (T-Mobile Vibrant and AT&T Capative) for a while now. First the hard way, then the easy (paid) method, then comes the easy and free method. I’ll just share with you the easy and free method. One day while I was looking for the paid method, I stumbled upon this:
Galaxy_S Unlock – http://tchlbs.tl/lWFR05. With this app, it’s a couple of clicks to perform the carrier unlock once you have root access, SU permission and busybox installed.
busybox installer (http://tchlbs.tl/lUg6yf) and install the lastest version of busybox.
Super Manager (http://tchlbs.tl/m4O7sT) a free app from the market and select root permission in settings to remove a few bloatware from system. Proceeded to then install busybox with busybox installer without a hitch.
