Just got a Wildfire and am about to take it back to shop again because I hate the quite large Android image (green alien) that appears on screen whenever I make or receive a call. Seems quite a childish feature - and inappropriate for receiving calls at work (or other 'serious' environments) where colleagues might notice it. HTC technical support tell me there's no way of getting rid of the stupid thing - unless everyone who calls me has their picture registered in my phone, in which case their picture will appear instead, but that's hardly realistic... Help!
