no data connection / internet

This morning I turned on my phone to check the weather. No data connection was available. I tried the below without success:
I am using JuiceDefender and tried turning off the app.
I checked my data connections and that data is enabled.
I then forced it to 2G.
I then turned off the data and turned it back on.
Turned off the phone and turned it back on.
Turned off the phone and pulled the battery. Waited 5 minutes. Put battery back in.
I went to work thinking maybe it was the location.
Uninstalled JuiceDefender.
installed JuiceDefender
verified T-mobile agrees that my account is paid up.

I have not rooted the phone. Wifi works fine and without any problems.

Any ideas for other things to check. Thanks.

Well at the end of the day the data plan was working again. Not sure what happened.
