Yahoo blames Microsoft for the Windows Phone 7 data usage issue

Looks like Yahoo isn’t really happy about Microsoft opening up and pointing at Yahoo’s Mail as been the culprit of the Windows Phone 7 data usage issue. The Search Eng…err no they are no longer a a search engine (Y! search is powered by Bing..)…the company has now sent a statement claiming that the problem was caused by Microsoft’s implementation of the IMAP protocol even though it has been shown that Windows Phone 7 is making relatively standard calls to the servers and that it’s Yahoo’s IMAP servers themselves who are then sending back unusual replies. Anyway, note that the statement itself has only been sent to one website and that it doesn’t look like the official PR line at all (Yahoo “officially” sent out to bloggers the same statement that MS sent out yesterday).
