Twitch update for iOS more than triples live channels, revamps chat

Twitch streams a lot of events these days, and it's improving its iOS app to keep up with the flood of new content. The just-posted 2.3.5 update more than triples the number of accessible live channels from 200 to over 750, giving viewers a better chance of seeing a local tourney or a "let's play" feed. Chat has also received a thorough makeover that brings both a simpler design and support for Twitch's unique take on emoticons. And if you're a dedicated Dota 2 player, you'll definitely want this upgrade -- link your Steam account and you'll earn item drops in Valve's arena battler when watching certain streams. There's no word of corresponding updates for Android or other platforms, although Twitch says it's improving channel capacities across all its apps.
