I want to use Tango on my Bionic (which I have successfully installed) and also use it on a PC so I can talk with my kids when I am on the road. When I go to install it on my PC it asks for a mobile number. Obviously I don't want to use MY mobile number because I doubt I can call myself (or can I)? Should I use my wife's mobile number even though she does not have a smartphone? Will that change anything about her phone (IE interrupt regular calls, add a data package to her account, etc...)? I gotta believe this can be done, I guess I just don't know how. Any advice is greatly appreciated.
