change the ESN

[roadskooter]

After I root the optimus, will I have the ability to modify the ESN and move my number?

I'm pretty sure ESN cloning/hacking/changing is illegal and its discussion is not allowed here.

If you're trying to port your number from another's carrier, you need to talk to Sprint directly.

drewwalton19216801 is correct. It is illegal. To answer your question, NO you do not have to root the phone in order to change it's ESN. Rooting your phone allows you to adminster your phone better and unlock features you normally wouldn't be able to. Messing with the phone's NV items (the radio, not the system) is not recommended, you can brick the phone.

You can have it flashed... (MetroPCS and Cricket are examples of companies that add the phone's ESN to their database and allow it's usage in their network.)
