No it won't. When a cell phone is bricked, it becomes useless. You confuse operator block with anti-theft block. The first can be undone, the second one can't.
In Europe, the system of bricking a stolen phone has been abandoned many years ago.
The reason is not commercial, it's purely technical. To trace a stolen phone, the IMEI number is used. But since the IMEI can be easily changed, you risk bricking someone else's phone. That happened years ago to some 6.000 phones which had the same IMEI, cloned from a Danish phone. When the Danish phone got stolen, the Danish operator bricked it, resulting in 6.000 Spanish phones no longer operating. And since you can't undo it, they had to be replaced. The one responsible for cloning 6.000 phones with identical IMEI numbers was a Dutch phone trader.
Anyways, there is no problem with cell phone theft over here, except people declaring their lost or broken phone stolen, just to get insurance to pay for it...
