I apologize in advance if this is the wrong forum for this question (and for the double post).

Can anyone recommend a GSM cellphone with Bluetooth that I can attach to the power adapter in my glove compartment and forget about? Something that will work reliably so long as power is coming in from the adapter, regardless of the state of the battery? Something I never have to worry about over-charging or under-charging the battery, opening the case and changing the battery out, etc.? Something that just simply works? It doesn't have to have (but if it does that is ok too) a camera or a color display or a display or even any buttons at all. If there is a special cell phone cradle or charger which can make this happen for me, that's ok too. I just want something that will work in my car when my car is on, that I can unlock and use with my prepay cell plan.

I've looked, but maybe I am just not asking the right question. It's hard to believe that with all the cell phones out there, that none of them can be guaranteed to function reliably whenever plugged in to a power source.

Thank you all for your time.
