I'm with you guys. I noticed today that I would lose my data connection when using many different Google services. Talk, GMail, and YouTube all cause my to lose my data connection (bars go grey from the normal blue, meaning I can make calls and do SMS, but I have no data connection).
Google Talk:
As long as I am on the main screen, I am connected and can see who is online and offline. As soon as I click on a person's name, I start to lose my connection. Occasionally I can get a message out before I lose my data connection, most of the time I can't.
GMail:
Messages come in on a LONG delay over mobile data, and when I am in the GMail application, I lose my data connection.
YouTube: The app loads, I can search for videos, I can even choose videos, but they will never load. I lose my data connection until I back out of Youtube.
All of this works just fine over Wifi.
Anyone have any additional information for us? When I noticed the problem, nothing had changed on my phone for weeks (I'm running Atrix CM7 nightly 20, which was released back before Thanksgiving). Tonight I did a full wipe in fastboot and reinstalled everything from scratch, and I have the same problem.
