Alas, not for everyone: Having sent the update to Ion developer phones just a few days ago, T-Mobile is commencing a gradual rollout that should finish up in the next few days. Here's what you'll get, with this Donut:
• Universal-ish search with an updated "Quick Search" box
• Much fast camera performance, with a refreshed interface, and easier switching between video/still modes
• Support for VPNs, corporate or otherwise
• A battery monitoring center that lets you see what apps are sucking inordinate amounts of power, and also lets you kill them.
• Multiple resolution support, for all the wild'n'crazy Android devices coming down the pike
• A new Market UI, with app screenshots
• Text-to-speech for any app that wants it, built into the main search widget by default
• A gesture framework for developers
• CDMA support, because, you know, Hero.
Let us know when your updates hit in the comments; reports are thin for now, but I have a feeling the floodgates are about to open. [CNET]
