Question : Changing properties of a Read Only field

CRM 4.0 - the attribute Price Per Unit in the Opportunity Product entity is Read Only by design.  I would like to change that so that the field is NOT read only.  I can't do that from within CRM.  I'm sure there is a way to accomplish this, but I haven't found it yet.  :)  Any help would be greatly appreciated.  Thanks.

Yup, as suggested by rakesh.

in the form onload event.
crmForm.all.priceperunit.Disabled = false;
