If you're rolling with the Instinct, you might have already noticed your applications prompting you for an update. If they haven't yet, they will soon. Some of the app improvements include a less sucky browsing experience on Yahoo, Hotmail, Best Buy and YouTube; faster, more responsive Sprint TV/radio; performance improvements for the Music Store; less crashy Picture Mail; and a bunch of other fixes. Deep down, we were kinda hoping they'd replace the browser outright. [Instinct Insight via Mobile Burn]
