You're probably getting that because you froze yahoo contacts and the authenticators. Freeze any of those using bloat freezer or anything that freezes apps, contacts won't work. And guys, wipe your battery stats after you charge it fully, then let it drain. Battery will drain faster right after update since the phone is getting used to the new firmware; don't expect instant perfection. Also, why don't you actually try using the built in task manager. For something moto pre-loaded onto these phones, it actually does a decent job.
