I am running a rooted 2.2 (blue energy with a 1 ghz kernal. I have an exchange account, google account and facebook all set to sync on demand (not when roaming though). Everytime I do a batter pull and the phone comes back on it takes forever to do what I think is syncing. And occasionally its rebooted in the middle as well.
I've been searching on the forums and really can't find any thing like this.
