Received PRL 51803, either yesterday or last night. Now I switch between 1X, no data, and 3G. I called CS, and they think its the phone. They had me do a factory reset, and it took 10 min to sync. with Google. I had a good 3G signal prior to the PRL update. Voice and Messaging seem ok. Any ideas? Trying to figure out if its the phone or service area.
