When I attempt to set my voicemail greeting, it first asks me to set a 4-7 digit password, then hit #. If I hit # without entering digits, it says "# is not recognized". The user manual clearly states "Sprint recommends you set a password, otherwise anyone who finds your phone can access your voicemail." That implies you don't have to set a password. So how do I tell it I don't want a password, and let me move on to the greeting recording? Thanks everyone - this is a very helpful forum here!
