BT's BluePhone - Not Myth

Thread Title:
Bluephone's Wi-Fi future revealed
Thread Description:

I posted on embedding skype into mobile earlier today, now thanks to slashdot i find techworld have the scoop details released by BT on the fabled "bluephone" - BT's infamous WiFi roaming handset:

How does Bluephone work?
The original idea for Bluephone was to have a normal cellphone which can send calls via a special Bluetooth base station when inside the house or office. BT chose Bluetooth for the job, because it supports cordless telephony, is less power-hungry than Wi-Fi, and is almost universally available in mobile phones.

Bluephone is a consumer service, and BT intends to deliver it on absolutely standard cellphones.

However, since the project was announced, Wi-Fi has been moving fast, and BT can see which way the wind is blowing. "In 2006, when Wi-Fi makes its way into standard mid-range phones, we will have a Wi-Fi version," says Ryan Jarvis, director of mobile products and partnerships at BT. Future versions will use WiMax, he says.

But, even when the Wi-Fi version arrives, this will not be the converged Wi-Fi/cell phone that we have been waiting for, because it will not do voice over IP, and it will not be a SIP phone.

Bluephone calls use the GSM network. When they transfer a call to use the Bluetooth link, they just transfer the first few yards of that call. The call stays under the control of the GSM network. All indications are that it will still be priced as a mobile call: Jarvis would not be drawn on pricing, but offered the possibility of "a discount" for calls using Bluephone.
