I'm on a custom ROM (cyanogenmod) with my optimus S..and when someone leaves me a voicemail message (on Sprint, not Google voice), I get a text message that says this:
(actually, it's two text messages, the first one says this):
//ANDROID:*@vvm.coremobility.com has sent you a Sprint Voice Message. Call 408-970-0000 to listen. MMSN,c351102d49d,41f,M68BzrH9Msi//CM
(then a second message that says)
//ANDROID:MWI Notif turnOff mdn:256*******
CFGs3201.0=09erbxzc0omb723xZThDj9//CM
I took out my phone number and replaced it with **** in the second message. Everything else is exactly as I receive it. WTF is this crap..I been getting it for MONTHS...if I even get notif of VM. Most times I don't get this at all, but the number it comes from (sender) is 9016
Curious.
