Exclamation Point on the Phone Icon

[Skeezix]

I resolved my problem:

When the phone strength icon has an exclamation point on it, it means that I have disallowed data when making calls, but I can still make and receive calls.

When the exclamation point does not appear, it means that I have allowed data when making calls.

Thanks for the info!

I'm still working on the procedure you asked me for sometime last week. Can't recall at the moment what it was but when I'm finished, I'll post it here.)
