Since I got my HTC incredible last December, I've been able to go into manual programming and zero out both my MIN and MDN. I work alot of jobs and sometimes need access to the HTC net and apps but can't afford to be bombarded with calls or emails. When I zeroed them out, I could have the phone on, but not worry about any messages/texts coming through until I reprogrammed the MDN and MIN back in. After a system update today, I can still program the MIN. But I am no longer able to manually change my MDN -- it's not even editable. Help? And as is, if I manually just change my MIN, do I still receive calls/texts? Cause I'm trying not to (at my own discretion).
