I tried #611 CS again. Operator told me he would remove my data plan and re-add it/activate. Told me to hang up and do another battery pull for 5 minutes.
Surprisingly, this worked. All applications work now. OS seems faster (might be placebo). Checked status, IMEI changed back to original. Not sure what happened.
Thanks for the responses, appreciated. Consider case resolved.

But what do I know.

I cannot see how the IMEI was changed, unless you used MFI.
