Ok, I don't have a signal and not had one for over 4 hours. I have the big red X where the bars should be and I have gone to the t-mobile store and got a new sim card and rest my bb soft (alt, del, caps) and pulled the battery etc. I travelled from Nashville, TN to Birmingham Al and about 1/2 way I lost my signal. when I rest it say searching for network then eventually comes up with no signal.

Anything else I can do?

Is it t-moble or my phone?

Check the threads my friend. Been discussed quite a bit today.

Seems there has been an outage that began sometime this morning and expanded nationwide this afternoon. I was back fro about 7 PM to 9 PM but am down not. No word of a fix or a time of when to expect things to get back to normal.

does this apply to phone service as well?

It might

While I was down it only affected my e-mail. SMS/PINs/Phone Calls weren't affected for me.
