Tweetium the first Twitter client to officially support 280 character tweets
(All About Windows Phone)

You`ll remember my unofficial way to post longer tweets in Tweetium last week? Well, this is now redundant as Tweetium UWP now supports 280 character tweets officially, in an update released just now. Notably, the official Twitter UWP client is still limited to 140 characters, so Tweetium is the way to go.
