In the ad, it says you can use a Nokia or 3650 type batter "if necessary" and "in case of emergencies". Not sure what this means! What I'd like to know is, once the original battery dies, can it be replaced with a Nokia phone battery (if so, whats the specific model no. of the Nokia battery)? Or a "3650" (whatever that is?)

Also, how long does the original battery play on music files before it has to be recharged, anyone know?

Finally, Im not sure how "portable" it is, since it seems to have no built in loop to hang a lanyard, and comes with no case. Is there a case or some means of hanging it around your neck? (Besides duct taping a rope to the back, I mean....)
