Just wanted to share a program duo that helped me speed up my DX2: So the built-in Task Manager in the DX2 has an "Auto-end list" where you can specify programs that should be automatically closed within two minutes of the display being turned off. I added lots of programs I was surprised to see had been running in the background. I didn't add any (like Pandora) that are sometimes used while the display is turned off. I then downloaded SystemPanel Lite from the Android Market to verify memory usage by application and found a few more to put on the Auto-end list or freeze with Titanium Backup Pro (including Calendar 2.2.2 and Cardock). Not sure if this has been posted yet, but I haven't seen it. I've seen a noticeable improvement in my phone's performance. And it might be enough to keep me from returning my DX2.
