I have a Sanyo Innuendo from Boost Mobile, but I am not satisfied with it, so I was planning to return it back (to Target). I bought it 1-2 days ago. The receipt says something about 45 day return on cameras, camcorders, and computer hardware. But what about phones? I activated mine and opened it already. And also, I have $17 left of airtime on there, do I get a refund too?
