My 3GS contract with Three {Vodafail} expires next week. So I will after 11 years with one company that has changed from Orange->Three->Vodafone will be looking for a new circuit provider... Probably Telstra.

At least that way I can get reception on my morning commute more often then not & in reception in the CBD.

So for me the 4S is a logical choice, just not the only one.
