BT's Converged Wi-Fi/Cell Phone

judgecorp writes "BT has been talking for more than a year about "Bluephone" - a cellphone that roams to a wireless network, when you are in the house. Just when we thought it was all hype and vapour, BT is revealing more details. Good news - it will move to Wi-Fi, when Wi-Fi handsets are cheap and good. The first version will still use Bluetooth, because Bluetooth works. Bad news - it's not a SIP phone, and therefore not really a converged phone. It doesn't roam calls onto the Internet, or even onto the landline, where they would be cheaper. Wi-Fi or Bluetooth is just an alternative for the first few feet of the call. Takes a few calls off the cell network, but doesn't do a lot for the user, apart from giving you just one phone to lose."
