Then i suggest you root ; it helps alot. All the stock games that come with the phone take up around 50mb of space ; I've moved both adobe flash player and google maps to sd, deleted stuff i dont use i.e. default browser,timescape,all the SE facebook stuff, most of my apps are on my sd card and all of my games run smoothly (around half my apps are games) , another thing you might want to look into if you decide to root is the supercharger v6 which really speeds up the phone ( no idea how laggy your phone may or may not be with that much free space).
