3's making big moves in Scandinavia with a little help from the gents at Nokia Siemens Networks and its Push to Talk and Presence solutions. The Push to Talk over Cellular (PoC) trial will start in the Swedish market with, yeap, Nokia PoC handsets. Push to Talk, for those not in the know, lets you use your handset like a walkie-talkie and get in touch with people with the click of a button. Presence services deliver real time updates for your contacts, so if a friend's in a meeting, you'll see his status is away and can choose to get in touch at a later time. Nice to see other places getting in on that joy -- though, judging by the pic attached, they're using it in the same room, rather like a conversation, but more impersonal (wink, wink).
