While chat apps excel at adding contacts from the online world, they don't cope so well with real life -- reciting and typing screen names isn't very elegant. Nokia is bringing back some of those social graces with its Nokia Chat 1.1 beta, which revolves around NFC transfers. If both friends own NFC-equipped Lumia phones, they can tap to exchange their own details, other contacts or even the app itself. It's also easier to share locations: contacts with Lumias will see a Here Maps-based preview of any given place. These additions don't make as much sense outside of an all-Nokia ecosystem, but there's certainly enough for existing users to upgrade at the source link.
