Hi, We're moving over in August, and in anticipation of having to drive around looking for streets while house hunting, I was going to buy a GPS/Navi device. Primarily I want it to find streets in Brisbane, but long-term I guess I'll want to use it out of the car for small hiking tours etc. Also, we'll need a mobile phone because we're staying in temporary accomodation at first which has a fixed phone line, but we'll need to make a few calls out and about. What experiences have people got using smart phones for car-based navigation? I got the impression that mobile services can be a bit patchy in Australia, although I would hope that Brisbane and its' suburbs should be OK. Any recomendation for a (not too high end) smart phone with GPS and a payment plan that allows you not to have a fixed address. Soemthing that only relies on a valid credit card, I guess. And where do you buy the phone? Is there any point in shopping around, or are most "phone warehouses" the same +-5%? Thanks.
