Best NextG Phone with external aerial

Looking for a next G phone for the 4WD

My wish list
1. A cradle so it can charge in the car
2. I can see the screen whilst driving to indicate if i have signal or not...i.e. no stupid screen savers or clocks.....signal level is much more important....
3. The screen backlight can be selected to be on all the time whilst in the cradle so I can read it during the day or at night
4. It will accept an external aerial preferably hardwired but I may consider a passive if people here find they function well.
5. The battery life is in days not hours...fancy colors screens are not required....
6. Blue tick (Regional/Remote) certified or equivalent

I will have an external aerial on the bullbar for the phone & run the cable back thru the firewall.

Oh & I just need to make phone calls on it & SMS, that's it!

I've been happy before with Nokias, but I don't think they have one at the moment with an external aerial connection. The advantage of a Nokia is that the crade has an insert that can be changed with new models so i have been told.....

Thanks
