Out on the town with your Lumia and eager to hook up with friends? It shouldn't be too hard to socialize after today. Skype has upgraded its Windows Phone app with a location sharing feature that lets you send your position to whoever you're chatting with, making it a bit easier to meet at the pub. The update is potentially important if your pals are overly talkative, too, since you can switch off notifications for individual conversations. Map sharing certainly isn't a new concept in the smartphone world, but it's hard to knock something that could liven up an otherwise dull weekend.
