I thought i would add my 2 cents here...
i was using AWD free version, and i was having similar issues with it being sluggish, lagging and choppy.
i have frozen the home.blur.apk with titanium, with no effect.
i read an earlier post about an app that you can download to get paid apps
so i decided to try ADW EX, just for giggles, and the difference in my phone was striking, all of the sluggish, lagging and choppy issues vanished, the phone is now fast and responsive.
now i'm not advocating downloading paid apps, but considering the difficulty getting just normal stuff to work, i do not have a problem with it in the case of the DX2. Sometimes it can take a while for issues to manifest themselves, sometimes a trial just doesn't cut it.
i will give this a try for a week or so, along with a different audio program and see if these issues do not return. If after a week or so of hard use and all is well, i will download the paid versions.
