I would love to see some windows smartphones in your line up. Ting is a great idea, but as of right now I have an iPhone, but i'm liking windows phones now. Maybe a Nokia lumia 920 or a HTC windows 8X. But having no iOS or Windows to me is hurting you a lot. Out of iOS, windows, and Android, I like Android the least. Having a Window phone would help you guys a ton and could potentially bring in a lot of money.
Get some Windows Phone
