If, like me, you switched your iPhone to 3 because they offered great plans and didn’t gouge for data and tethering like Optus and Telstra, but found their coverage patchy at best, and their roaming data charges obscene and unavoidable, be aware that they will switch you to Vodafone on a cheaper plan for basically the same data and call cap. You pay for only the cost of paying off the phone – which could end up costing you nothing due to plan savings and no roaming data charges. Just make sure they unlock the phone from their network before porting your number!
