There was an app that was available for the 2.1. After the 2.2 update, the dev pulled it off the market (on the 23rd), because it was making the DX's buggy. I never installed the app because I didn't know about it until about an hour after the dev pulled it. Lol. A few short days later, it was back on the market modified for the 2.2 ota update, minus a few features the dev was working on. A coupledays after the new version (9/27), a second update was made available. IMMEDIATELY AFTER I UPDATED AGAIN, my phone became buggy to the point I had to do a factory reset this morning. I will reinstall the app in a couple of days when I have more emails and texts in my inbox, along with an adequate history to compare to. I emailed the dev yesterday and told him I suspect the app caused my phone to go buggy. I will wait for a response before I put him on blast. I don't want to ruin his business and I turn out to be wrong. If I don't get a response, I will email him again and let him know I plan on putting him on blast. If no response, I will update this post with the name of the app to avoid. The bad part about it is, its a really good app, and I hope I'm wrong!
