So I'm beginning the battle of starting to use my new Palm Treo Pro. After doing some reading I'm not even going to attempt getting it to connect to the car so current thought is to get a 2nd sim and leave my old Nokia 6310i in the UHI cradle in the car (facelift W203 with COMAND). I realise I could manually set and unset divert every time I get in and out of the car, but what I'd like to do is leave the Palm set to divert on no answer then I could just rely on that without having to remember. However my issue is that that would mean all voicemail messages would go to the 6310i's number. So, two questions: 1) is there anyway of forcing the messages back to my main number's voicemail box? 2) is there a better way of doing this.
