Windows Phone 7 January update bringing copy-and-paste, additional minor improvements
Microsoft, however, has now posted an official "sneak peek" at what's on the way. Copy-and-paste is perhaps the biggest addition, though faster application and game launch times will be a welcome improvement as well. Marketplace search has also been tweaked -- tapping your phone's search button post-update will allow you to search the specific category you're currently browsing, rather than the entire Marketplace.
Bigger updates like in-app purchases, expanded APIs, Internet Explorer 9, and Silverlight support won't happen until some time after Mobile World Congress 2011.
