Here's a thought to plant into the minds of the technogeeks at 2 degrees and their marketing overlords. Now that 2 degrees is getting into the broadband market, perhaps a method could be developed to make calls through broadband. This would help solve the poor reception issues for some of us.
This could either take the form of making calls directly through wifi and home broadband (I believe iOS has this potential) or perhaps selling a femtocell device for the home. Vodafone offered the latter option at one point but I don't know if they still do.
Cheers,
