Full of misinformation here. Microsoft doesn't snoop anything, its google that does and then sells ur information and contacts to advertisers, this was all over the news recently. U should be able to get the mango update on the arrive very easily. Maybe u already have it, what does it say under about?

If that doesn't work try installing Zune again and maybe try to get sprint to replace it with an arrive that has mango already on it. Do this before giving up as there are really great things planned ahead for the windows ecosystem.
