Two days in a row I've went to bed and woke up to the touchscreen on my DX being unresponsive. Apps Running: FeedR, Tweetcaster Pro, Springpad, and Gmail App. Wifi on, and GPS off. Any Ideas? I got the DX on the release date 15th so my 30 days are about up. Should I call and request a new phone? Will I get a new one or will they try and send me a refurb? FYI: I have to do a battery pull to get it to work again.
