I have a questions about the signal quality and antenna quality in the Hero. My wife and I left AT&T to try the Incredible b/c we were getting sick of the iphone and apple. We loved the phones as smart devices, but had serious issues with call quality. After 3 weeks and each going through 2 phones we decided to try sprint and the Evo. To do so we had to come over early and grab Heros for 2 weeks until the Evo comes out. I've noticed over the last 4 days with the Hero that i seems to be having a very poor signal to the point of calls going directly to voicemail where my iphone and the incredible got decent to very good service. Is this a problem with the antenna of the Hero? Will the Evo most likely have a better cell antenna with the addition of the WiMax antenna? Or is this more indicative of Sprint's cellular footprint? I'd appreciate any feedback i can get as I don't think I could go back to an iPhone after having an Android for a month and seeing what's coming with Froyo, but not sure what other options I have other that the Incredible and Evo.
