Our VZW cellphones have lousy coverage in our new home. I was told I could get a network extender and my research landed me on this site: http://cellphones.lovetoknow.com/Wireless_Network_Extender . Has anyone had firsthand experience with one of these they'd care to share? Seems to me the sound quality would suffer due to too many conversions, i.e., the "hybrid VoIP". Also, would this effect the quality of texting?
