The WP7 used to display it in the phone settings, but I cant find it in my HTC8x. Where can I view what my own number is?

[Muessig]

It's in Settings>About>More Information> MDN: XXXXXXXXXXX

[SRRAE]

Mine doesn't have MDN in that location

it shows it on my htc 8x in the location described above, when you click the more info button, its above the IMEI number

Actually click the phone tile to bring up call history, hit settings and it will display your phone number and other call settings, its no longer on the cellular option under settings

Just checked on my 920 and it does show the mdn on the about option in settings, thanks for the heads up muessig
