Hi,

If you have only 1X, then phone calls is all you can make.  You do not have a data signal.  Since you said you tried the battery pull already, then resend your service books.  Go to Email Settings>Press the Menu key and select Service Books.  Then click Resend Service Books.  After that, you may have to do another battery pull.  If that does not do the trick, then try updating your PRL.  Dial *228 and select option 2.  Let me know how things turn out.
