Apm'd and SunRocket MVNOs leave customers networkless

Another one here by Om that I wanted to document:

Link: GigaOM What about the people? «

Sometime later today, there is a good chance Amp’d, the beleagured mobile virtual network provider will turn off its service, leaving over 100,000 of its customers in the lurch. A few days ago, SunRocket shuttered its doors, leaving 200,000 subscribers in the lurch.

I’m sure their MNO parents — whoever’s backbone these customers are actually using, will be delighted to welcome the subscribers and maintain their mobile service…?
