Netgear announced the SPH200W, a wifi Skype phone that sports 802.11b/g compatibility. This phone will give its users ability to make calls at wifi hotspots or open signal, using Skype. However, it does not contain a web browser, therefore it cannot access hotspots that require web-based login or authentication.
Furthermore, the SPH200W also has WEp/WPA/WPA2 support and has a built-in speakerphone. You will have to wait a bit for the price of the phone though.
