I'm looking at picking up a spanking new HTC Hero this week. T-Mobile have far and away the best deal on tarriffs, but I've heard that their signal quality is a little naff. Is this the case? Anyone know when 3 are releasing the HTC (and is their signal quality any better)? The only provider who I know to be of decent quality, and who offer the Hero, are Orange, and their prices are pretty high...
