Glad I found this post. Thought I was going crazy. Updated with tbh 2 part. Damn phone has be restarting for about 4 days now. Actually saw the booger do it once. Battery pull and no issue for last 24. 2nd X still on froyo, still not a single issue.
While there are many reporting this issue (see MOTO link above) not all have it and don't understand why. Wonder if anyone with a rooted phone or different launcher have this issue. I have a completely stock phone.
