I have an old LG 2X that on paper should be a fairly good phone and I have read online they they can be pretty good with the right ROM. But with the standard OS its pretty horrible. Normally I leave my devices well alone for warranty purposes and for the fact I have always had high end phones so they have performed well out of the box. This phone will be for my wife to use and will be her first smart phone so I would like it to run smoothly and not stall or lag etc so I don't ruin her smartphone experience!

Can anyone recommend which ROM would be best to use on it?
