Unlocking a cellphone can be a headache, so we're pleased to see Samsung has done its users a service with the Galaxy S - and the US versions, the AT&T Captivate and T-Mobile Vibrant, based on the phone - by including the unlock codes in a file on the smartphone itself. Unfortunately they've not made them easy to access, and so the team over at xda-developers has stepped in with a simple tool that takes a locked Galaxy S family handset and spits out an unlocked version.
Best of all, there's no need to root your phone beforehand, and the whole process is reversible should you need to return your Galaxy S to the carrier at some point. Obviously any modification of this sort runs the risk of leaving you with a bricked phone - and we can't see too many warranties holding up to unofficial tweaking - but the reports in general seem pretty positive about the unlock's stability.
