Recently I am having problems with my og Droid not receiving calls because of poor signal in my apartment. I am due for an upgrade and have been looking at the thunderbolt. Will 4g provide a better signal? I know data is faster but will the reception be stronger? My area does have 4g coverage. I also heard HTC phones have better antenna designs than Motorola so they naturally provide better reception. Just wanted to see if this is true before I get a new phone. Thanks!
