I can't help but feel like not having data while using voice would be a bigger annoyance to me than Gruber found it. I often look up maps while on the phone with someone. Also losing wi-fi during a call could be frustrating.
I completely agree. I use data fairly regularly when I'm on the phone. That is enough of a factor for me that I don't think I could switch until it gets resolved with Verizon's network updates.
WiFi and calls work simultaneously, it's only 2G/3G data that's affected.
I think that yesiamahuman meant the hotspot tethering functionality by 'WiFi.'
