  1. Great guide worked perfekt.

  2. Nice read. However, gingerbread isnt totally smooth on Gio. It runs Froyo absolutely fine. I wouldnt recommend updating to gingerbread unless you are bored as there are lagging issues after updating

    • I haven’t had any issues with gingerbread on my Gio. Oh except I’ve lost my facebook shortcut and the wi-fi turns itself off if you haven’t used it for a while. If you go back into wi-fi settings it restarts itself. If you use the drop down bar it says it’s still on so you need to turn it off and on again.

  3. Is it safe to try this rom on gio s5660m not s5660x
