Yikes! 2 - 5 MB used per hour. That would be about 1.4GB a month, with the phone just sitting on a table (assuming the 2MB figure)!
Windows Phone 7 users are complaining over what they call "phantom data usage." The nascent smartphone platform is, according to some accounts, using as much as multiple megabytes per hour of cellular data, and that's even when connected to wi-fi.
Indeed, you read that correctly; even when connected to wi-fi, Windows Phone 7 seems to be defaulting to cellular connectivity when there's a wi-fi network that the users's phone is connected to.
This is probably a bug that will be fix with Microsoft's first big Windows Phone 7 update that should be coming very soon. Until then, WP7 users are seeing what happens sometimes to early adopters.
