Windows Phone 7 isn’t even out for a year just yet, and here we are with whispers of Windows Phone 7.5 on the horizon – sometime in January 2011, to be exact. It seems that there might be another update which could also happen sometime during Mobile World Congress, although recent news seem to point towards these to include mere bug fixes and minor tweaks, with a much meatier update to happen in August or September. Heck, might this even be the “Mango” update that we talked about earlier this morning?
