Using the ##778 to change some settings I also stumbled upon Display > Warranty Date Code. This seems to me to show the date I ordered the phone...and therefore the reference point for my 30day return period, warrranty, etc. Even in editable mode (using password 000000) it is not an entry that is editable. Does anyone know if it is possible to change the value for Warranty Date Code? And are you thinking what I'm thinking is possible?
