The problem surfaced in early January with some owners of phones running Windows Phone 7, claiming that their phone was sending 'between 30 and 50MB of data' every day; an amount that would eat into a 1GB allowance in 20 days. Microsoft said its investigation found that most problems were caused by a unnamed 'third party' service. It said that the problem seemed to only affect 'a small (low single-digit) percentage of Windows Phone customers.'"
