how to remove phone number from old phone

[UTnick]

is there a way to remove my phone number from my hero before i sell it? i just feel weird leaving it on there and sending it to a stranger.

You can wipe it..? Restore to factory defaults in the settings should solve it..

Gonna assume a CDMA Hero
Call your carrier, make sure the phone is released from your account, and factory reset.
