Thanks to the developers who have been working with jail broken apps, Facetime over 3G is available for any old IPhone 3Gs. This is still very big since the IPhone 4 does not yet offer over data Facetime, but now with this app if your IPhone has been jail broken then you can use Facetime over your data. This is however not the best thing for the IPhone 3Gs which does not have a front facing camera on it like the IPhone 4. If you feel it is worth your time to video call with minimal face to face conversation then go straight away to download this app off of Cydia. I would not bother with this unless I had maybe a mirror to reflect myself off of so that I would be able to virtually interact with someone on Facetime virtually face to face.
