Art has an older Motorola 4G phone running Android, and he wants to use it just for Wi-Fi access. Leo says that'll work great and with voice over IP apps like Skype and Tango, Art can also use it as a phone when it's connected to Wi-Fi. Art is wondering about using Google Voice with it. Leo says that Google Voice wants to confirm a cellphone number so that won't work right. Skype is good because for $100 a year, he can have his own phone number.
