New Verizon Customer *86 tip
I couldn't find a post related to this topic here regarding the droid. I am 30 days into my droid or so and my wife and I discovered that calls to check your own voicemail using *86 show as used minutes on the bill. Calls to your own number, however, route straight to your voicemail box and count as a free call to a verizon user.
You can change your default voicemail dialing number in Settings | Voicemail settings | Voicemail number. Just change *86 to your verizon number.
Hope this is helpful to some new verizon folks.
