generally any wifi phone will not let you use the wifi signal to make calls through your cellular account. this is UMA ofer wifi. UMA stands for Unlicenced Mobile Access. its a Benefitial feature where it captures the Wifi and uses it as an alternative to cellular signal, which is a benefitial for areas where cellphone service is spotty or lacking, you call out from your existing number, you use your existign handset, no complicated scripts or apps to install, and your caller sees your number, and not some crypted number they wont recognize. its not advertized or intended to surf the net for free over the wifi, so just tink instead of a GSM/WCDMA Antenna, ur using a Wifi antenna to make your calls, simple principal to understand.

Thats fine that you want to use wifi and surf the net for free on your phone, but your limited to only e-mailing your friends when your using wifi, and not everyone uses e-mail, if you want to call them, you must be in your CDMA coverage zone, so the wifi doesnt help you in your case.

QOS is perfect on UMA, I beta tested it before it went public.
