Re: my cel phone was stolen, I have the imei and i want to blacklist it or block it
Also file a police report. It won't get your phone back, but if someone is arrested with your phone, they'll add a larceny (or even robbery if it was taken from your person or when you were present) charge (and then you'll get the phone back, and you can get it un-black-listed). And you can claim it as a casualty loss.
