I held off on rooting because my Eris was working pretty well, but lately started to lag severely. So I used the 1-click method to root (Thanks jcase!) and now have xtrSense installed. Good-bye lag! Thinking back on my previous setup, I think I know what caused the lag (and might be true for others as well). On my Accounts & Sync list, I had 2 instances for Facebook. 1. Facebook for HTC Sense and 2. Facebook for Android. I'm not sure why there were 2, but I think these two were conflicting with each other and creating the lag. I noticed my contact's Facebook images randomly changing, or being deleted. Now I only have Facebook for HTC Sense listed and the images are consistent. Any one else with stock have these 2 instances for Facebook?
