BTW, i think for the same m910, Sprint's dialer has the logic to read ##7887# (which VM dialer obviously doesn't, at least not that number) and kick off DM app (which may or may not be there at all in VM m910). Both dialer and the DM app is in the ROM.
You can try flashing Sprint ROM and see if that gives you what you want. Make sure the ROM package will NOT write to radio (otherwise your phone will become an exact Sprint phone with VM branding). Take this with grain of salt, I'm just throwing in idea and you're responsible for the results of your own action.
WELL thats is exactly what i want to convert this phone into a sprint phoen so maybe i can get those options that iam missing. where can i get the sprint intercept factory ROM that installs via download mode or what ever mode?
