Just found this out yesterday. Go into services and turn off Background Intelligent Transfer Services. (BITS) It will turn off all updating; calendar, alarm clock, and a bunch of other crap. With it turned on, I was looking at 300-600KB per second download in the background. When using AT&T or Verizon connections, you have monthly limits. That goes fast at those speeds. With it turned off, I have speeds that average less that 250 BYTES per second. Much better!!
