What MVNO would you recommend?

Hey, I live in the U.S. and I'm looking into retiring my iPhone 4S and picking up a Nexus 4. I also figured this is a great time to get off of Verizon. I was wondering what carrier would you recommend?

Note: I live in the northeast CT to be specific.

Looking for:

  • Cheapish (currently paying $80/mo for unlimited data/text + 700 minutes (grandfathered in)
  • No contract (obviously)
  • HSPA+ (not a solid requirement, but near enough)
