Skype Wi-Fi Phone full review
From a technical point of view the Edge-Core works perfectly well. It looks like an ordinary mobile phone, but instead of connecting to a phone network it uses WiFi technology to connect to the internet over any wireless network. The Skype software is already installed on the phone, so you can make a call without even having to turn on your Mac.
The printed manual is a bit skimpy, and we had to go delving into the PDF manual on the CD-ROM in order to get the phone set up properly, but that was the only problem we encountered.
